AP SSC 10th Class English Solutions Chapter 3A The Journey 1

As I sit here alone and waiting
I gaze at people passing me by.
I try to smile and reach out to them
But no one notices; no one waits.
They look to me like I am nothing
Are they afraid to be seen saying “Hi”
to an old man like me?

Question 1.

Question 2.
How do people respond to the old man’s smile?
Answer:
When the old man tries to smile and reach out to others, no one notices and no one waits. They look to him like he is nothing. The old man feels that they are afraid to be seen saying “Hi” to an old man like him.

Question 3.
How should old people be treated so that they do not feel neglected?
Answer:
The old people should be treated equally. They should be respected and treated with honour. They should not be bullied or laughed at. We should share our feelings with them. We should give value to their feelings. We should obey them and try to follow their pieces of advice. If we treat the old people as mentioned above, they don’t feel neglected.

I. Answer the following questions.

Question 1.
‘After spending a leisurely Sunday at home, the very thought of returning to work on Monday is tiring.’ Do you agree? Have you ever felt so?
Answer:
Yes, 1 agree to the above statement. After spending a leisurely holiday at home, the very thought of returning to work on the next day is tiring to anyone. I have felt so many a time. I felt so after Dussehra holidays, Pongal holidays and summer vacation previously. It would be a difficult day for me going to school on the very first day after the holidays are over.

Question 2.
The last sentence of the first paragraph and the first sentence of the second paragraph appear to contradict each other. What could be the reason for the change in the decision?
Answer:
The last sentence of the first paragraph says that the author didn’t want to go but the first sentence of the second paragraph says that the author decided to go finally. Both the sentences contradict each other. At first he didn’t want to go as he had got married. He didn’t want to leave behind his newly-wed wife. But, when he remembered his increased responsibilities because of his marriage and his debts, he decided to return to work.

Question 3.
‘Why did the author get into debt? Think of some possible reasons.
Answer:
The author felt that he had got into debt after his marriage.
The possible reasons are :
i) The author might have met his marriage expenses.
ii) He spent leisurely at home for about six months without going to work.
iii) The increased expenses for the new couple.
iv) The author might have bought new furniture.
v) He might have bought a new flat.
vi) He might have bought a number of sarees for his newly-wed wife.
vii) He might have spent money carelessly.
viii) He might have given money to his old parents.

Question 4.
Why was the author reluctant to carry his own luggage? What would you do if you were in the author’s place?
Answer:
The author was reluctant to carry his own luggage as he had the feeling that if he carried the luggage, the whole world would laugh at him. He thought that his education had made him shun physical labour. In fact, the author looked for someone’s help. He felt that his guilt, shame, self-consciousness and pride might have stopped him from carrying the luggage. If I were in the author’s place, I would not do like he did. I would myself carry the luggage without looking for others’ help.

AP SSC 10th Class English Solutions Chapter 3A The Journey

Question 5.
The author feared that the whole world would laugh at him if he carried the trunk. Was the fear imaginary or real? Give reasons for your answer.
Answer:
The author feared that the whole world would laugh at him if he carried the trunk. I think his fear was imaginary. No one laughs at us when we do our work. In fact, carrying the trunk should not have been such a worry for him. For a young man like the author it should not have been an issue to carry his luggage on his back. Actually the others will praise his modesty, if he carries his luggage himself.

Question 6.
Choose one sentence from the story that best expresses the author’s false prestige. Support your answer with details from the story.
Answer:
“Somehow, I had the feeling that if 1 carried the luggage, my father and my people, in fact the whole world would laugh at me and I would be belittled,” – this sentence expresses the author’s false prestige. He thought that his education had made him avoid physical labour. As a government officer, he didn’t accept the idea of people seeing him carry his own luggage. He was of the opinion that it was through him that his parents had earned a greater degree of admiration and respect from the villagers. He felt that his father would not like to see him carrying a trunk on his back and would be very hurt if he did so. These are all the facts which show the author’s false prestige.

Question 7.
What does the phrase ‘opposite directions’ in the last sentence suggest?
Answer:
When the bus started moving, the author saw his father gradually receding into the distance. The author felt that their journeys started in two opposite directions, with him seated in the luxurious seat of a bus and father walking back with tired legs on the pebble-strewn road. The phrase ‘opposite directions’ suggests that both their directions were different. Actually, the son and the father had to travel in opposite directions to reach their destinations. In the other sense, the writer’s way was a luxurious one as he was an educated one and a government officer. He didn’t need to lead such a hard and laborious life like his father used to lead. When compared with his life, his father’s life was much harder one.

Question 8.
How was the story told? Were the events narrated in the order in which they had happened? Spot the sentences where the course of narration changed its direc¬tions. How effective was it?
Answer:
‘The Journey’ is a beautiful narrative by Yeshe Dorjee Thongchi. Most of the events were narrated in the order in which they had happened. Here and there we find that the narration changed its directions.
The sentences where the course of narration changed its directions:
a) “I did not have much to carry byway of luggage – just a trunk. Ours is a hilly terrain
Here the author tried to give the reason. Then he explained the purpose of his coming to his place. Thus, the course of narration was changed.
b) “Nobody had time to spare for me. In fact, carrying the trunk should not have been such a worry”
The course of narration was changed after the first sentence when the author tried to tell us about his inner feelings.
c) “We were walking up a narrow hilly road and neither of us uttered a word as if we were strangers who spoke different languages. I did not know what was going on in his mind.”
When we observe the two sentences given above, the first one changed its direc¬tion when the author tried to present his thoughts.
d) “Father wanted to say something but the bus started moving.” Later the narrative was changed its course when the author tried to think about his way in comparison with his father’s.
A reader could understand very well about the author’s inner thoughts by this way of narration. He too would try to think in his own way imagining that if he were in the author’s place. Thus it was effective in provoking the thoughts.

II. Write the number of the paragraph that gives the stated information in each of the following sentences.

1. The author enjoyed his married life.
Answer:
Paragraph 1 (The first paragraph)

2. The author tried to convince himself that he had not done anything wrong.

3. The author was ashamed of making his father carry his trunk.
Answer:
Paragraph 10.

4. The author looks at himself and his father as two travellers taking two different roads.

1. The author offered to carry the trunk for some time.
2. The author could decide on whether to allow his father to carry the trunk or not.
3. The author took unpaid leave.
4. The father was not happy with the old shoes his son gave him.
Answer:
Corrections:

  1. The author didn’t carry the trunk at all throughout the story. His father carried it all the way.
  2. The author decided that it would be better to let his father carry the trunk.
  3. The author initially thought of taking unpaid leave but later he decided against it.
  4. The father was happy with the old shoes his son gave him. His face lit up with content-ment when he noticed the author taking out his pair of shoes from the trunk.

Vocabulary

I. Look at these words from the story :

1. newly-wed wife
2. bus stop
3. forehead

They are all compound words. A compound word is a union of two or more words to convey a unit idea or special meaning that is not as clearly or quickly conveyed by separated words. As shown above, compound words may be hyphenated, written open (as separate words), or written solid (closed). The use of compounding in English is an evolving process. As expressions become more popular or adopt special meanings, they follow a gradual evolution from two or more separate or hyphenated words to single words.

audio visual audio-visual audiovisual
copy editor copy-editor copyeditor
wild life wild-life wildlife

The words in the first, second and third columns are called ‘open compounds’, ‘hyphenated compounds’ and ‘closed compounds’ respectively. In this unit we focus on hyphenated compounds.

A hyphenated compound is a combination of words joined by a hyphen or hyphens. Here, the hyphen aids understanding and readability and ensures correct pronunciation. Words are hyphenated mainly to express the idea of a unit and to avoid ambiguity.

AP SSC 10th Class English Solutions Chapter 3A The Journey

A. Pick out all the compound words from the story and group them under the head-ings as explained above.

Open compounds Hyphenated compounds Closed compounds
1. bus stop 1. newly-wed 1. anyone

Reduplicatives are used in a variety of ways. Some simply imitate sounds: ding- dong, bow-wow. Some suggest alternative movements: flip-flop, ping-pong. And some intensify meaning: teeny-weeny(very small), tip-top(very good).

Find the meanings of the words you like and use them in your own sentences. You will find similar words in your language too. For example, in Telugu, we have words like chi-chi, pho-pho, kaadu-kaadu, tara-tama, taado-pedo, pilla-jella, auto-ito. Give some examples from your language. Don’t they sound musical?

Grammar

I. In this story the author used past perfect tense (had + past participle) in many sentences. If you observe the following sentences from the story and the rules given under them, you will understand why and how the past perfect tense is used.’

1. It was 10.20 My father had already left, (para 6)
Answer:
When an action takes place before a point of time in the past, the action is expressed in the past perfect tense. (Sometimes the point of time can be understood from the earlier sentences and other contextual clues.)

2. Finally we reached Dirang. The bus from Tawang had not yet reached Dirang. (para 11)
Answer:
When two actions in the past are clearly separated by time, the earlier action is expressed in the past perfect tense.

AP SSC 10th Class English Solutions Chapter 3A The Journey

3. I quickly sat down on a rock. My father laughed at my plight, (para 7)
Answer:
When two actions in the past happen simultaneously, both of them are expressed in the past tense.

4. a) Sunitha never saw a bear before she was transferred to Maredumilli. (not from the story)
b) Shindh closed the doors because she heard loud noises from outside.
c) I never met him after I left India.
Answer:
Normally, when the time relation is unambiguous, (by the use of before, after, because, etc.), the simple past (past perfect is optional) is used to refer to both past actions.

Comment on the use of the simple past tense/past perfect tense (as illustrated above) in the following sentences. Identify the tense and give reasons for the use of the tense used.

1. I had come home this time round for a special purpose: to get married. My parents had arranged my marriage according to the customs of our tribal society.
Answer:
In both the sentences, the part perfect tense is used as those two actions had already completed before his narration, (had come, had arranged)

2. Time flew, and five months into my marriage I realized it.
Answer:
In the above sentence both the verbs are in the simple past tense as the time relation is unambiguous and those two occur in the past simultaneously.

3. But after some dilly-dallying I finally decided against it because marriage had increased my responsibilities and I had got into debt.
Answer:
“Marriage had increased my responsibilities and 1 had got into debt.” – These two actions occurred before “I finally decided against it.” Hence, in the earlier two actions the past perfect tense is used while the simple past tense is used in the latter.

4. On my way home from the bus stop my trunk had been carried by a porter, (para 3)
Answer:
The above action occurred before his narrating the story. Hence, the past perfect tense (had been carried) is used.

5. A large crowd gathered at our place the day I was to leave. People had come to wish me luck, (para 6)
Answer:
A large crowd gathered at our place the day I was to leave. → In this sentence the simple past tense is used as it occurred later.

People had come to wish me luck. → In this sentence the past perfect tense is used as it occurred earlier.

People had come and then the large crowd gathered. Hence, the two tenses are used.

6. Father was quiet for some time. He thoughtfully looked at the sun for a moment, and then his eyes fell on the can of home-made wine that I was carrying, (para 9)
Answer:
The actions in the above sentences occurred in the past simultaneously. Hence, the simple past tense is used in all the actions except the last part of the second sentence. ” ……….. that I was carrying.” Here the past continuous tense is used as it was going on at the time of narrating.

7. I gave him the can of wine. He poured himself a mug and handed me the can. He drank all of it at one go. He then arranged the belt that was attached to the trunk carefully on his forehead. (para 10)

8. I had never got used to physical labour having stayed in hostels right from my childhood. (para 11)
Answer:
“I had never get used to …………”
Here the past perfect tense is used as the author while narrating, went intq the past and told. Hence, the past perfect tense is used.

9. His feet had developed cracks and somehow resembled those of an elephant. (para 14)
Answer:
When two actions in the past are clearly separated by time, the earlier action is expressed in the past perfect tense. “His feet had developed cracks” …. This action took place before “his feet resembled those of an elephant.” Hence, the earlier action is expressed in the past perfect tense and the latter is expressed in the simple past, (had developed, resembled)

10. I noticed this for the first time. 1 hadn’t noticed that the road was uneven, (para 14)
Answer:
“I noticed this for the first time.”
Here the simple past tense is used as it is the author’s narration.
“I hadn’t noticed that …….. ”
This action might have occurred if the author did it but this action didn’t take place. Hence, the past perfect tense (+ not) is used.
” the road was uneven.” The condition of the road was mentioned here. It was
the condition of the road when he narrated. Hence, the simple past tense is used.

11. I checked my wallet and saw I still had around Rs.40 with me. (para 14)
Answer:
Both the actions in the above sentences occurred in the past simultaneously. Hence, the simple past tense is used in both the contexts.

Writing

I. In the story ‘The Journey’ the author says “…. my education had made me shun physical labour”. This is an adverse effect of education. Now write an essay on ‘The Adverse Effects of Education’. Here are some points:
Effect on
• doing some work that involves physical labour
• dress/fashion
• family relationships
• giving respect to elders
• the treatment of illiterate people
Answer:

The Adverse Effects of Education

It is a well-known fact that education plays a vital role in bringing up both economically and socially. It is thought that education helps people in so many ways. Highly educated people are enjoying the status in the present day society. People with high education attain a good job, more money and many other benefits. A literate person can show the right path to others. We usually think of the benefits of education only but we should not ignore the adverse effects of education.

When the pupils spend all their time in reading and writing, there is no scope for them to do any other work. They don’t find time even to play games. Their education makes them physically weak. They are unable to do any work that involves physical labour. “A sound mind in a sound body” is a proverb. Both the sound mind and the sound body are needed if one desires to be successful. When we are helathy, we can perform our functions regularly and properly. Today, most of the pupils stay in hostels right from their childhood. Hence, they never get the chance to do physical labour. One’s physical labour will make oneself both physically and mentally strong. But today’s education system doesn’t allow the pupils to do physical labour. And the other thing is that the educated people think that others will laugh at them if they do any kind of physical labour. They think that theirs is an important position in the society. Doing their own things is the point of prestige for them. Their false prestige makes them think in a wrong way.

The second point is their dress sense. The persons with high education try to wear fashionable dresses which are different from other ones. As far as the educated Indians are concerned, they give more value to the western culture. They try to adapt the foreigners’ culture. They never think of our culture and traditions. They think that only illiterate people wear such kind of dresses which reflect our culture. In their view, they will be degraded if they don’t wear modern dresses. This thought only leads to other social problems. The young women’s dress sense will cause them a threat. They think that they are superior to the uneducated ones and behave arrogantly.

Another important point is how education affects the family relations. When a person completes his education, he starts thinking that he is greater than the other uneducated members of his family. He wants to show his dominance. If he gets employment, he doesn’t find time to spend with them. He always thinks about earning money. He gives importance to money only. He doesn’t show any love and affection even for his parents. Thus, one’s education leads to the absence of human relationships.

Most of the literates don’t give any respect to elders. As Indians, we generally have faith in our values, traditions and culture. What we have learnt from our ancestors is that we should give utmost respect to our elders. At present, we witness a different scenario. Some educated persons think that there is no use of elders. They forget the sacrifices made by them. They ill-treat their family members who are illiterates. This will lead to the destruction of family relationships.

No doubt, there are so many advantages with the education one gets. But one’s education makes one senseless. The educated persons must not move away from physical labour. They must do some work that involves physical labour. They should take care about their dress. They should not deviate from our traditional way of dressing. They should maintain good family relationships. They should respect elders. They should treat the illiterate people with courtesy. Then only their education is meaningful.

II. Summarising

A few guidelines and tips to summarize a text are given below. Read them carefully. Then read the essay ‘On Umbrella Morals’ and summarize it.

Guidelines and tips to summarize a text

To summarize is to condense a text to its main points and to do so in your own words. To include every detail is neither necessary nor desirable. In order to write a good summary, you may have to gather minor points or components of an argument from different places in the text in order to summarize the text in an organized way. A point made in the beginning of an essay and then one made toward the end may need to be grouped together in your summary to concisely convey the argument that the author is making.

On Umbrella Morals

-Alfred George Gardiner

A sharp shower came on as I walked along the street, but 1 did not put up my umbrella. The truth is I couldn’t put up my umbrella. The frame would not work for one thing, and even if it had worked, I would not have put the thing up, because it was falling to pieces and I would be the laughing stock. The fact is, the umbrella is not my umbrella at all. It is the umbrella of some person who I hope will read these lines: He has got my silk umbrella. I have got the cotton one he left in exchange. I imagine him walking along the street under my umbrella, and throwing a scornful glance at the fellow who was carrying his ugly thing. I dare say the rascal laughed silently as he eyed the fool with his cotton umbrella. He is one of those people who have what I may call an umbrella conscience.

I hope you know the sort of person I mean. He would never put his hand in another’s pocket, or forge a cheque or rob a cashbox —not even if he had the chance. But he will swap umbrellas, or forget to return a book, or take a rise out of the railway company. In fact he is a thoroughly honest man who allows his honesty the benefit of the doubt. Perhaps he takes your umbrella at random from the barber’s stand. He knows he can’t get a worse one than his own. He may get a better one. He doesn’t look at it very closely until he is well on his way. Then, “Dear me! I’ve taken the wrong umbrella,” he says, with an air of surprise, for he likes really to feel that he has made a mistake. “Ah, well, it’s no use going back now. He’d be gone. And I’ve left him mine! “It is thus that we play hide-and-seek with our own conscience. It is not enough not to be found out by others; we refuse to be found out by ourselves. Quite impeccable people, people who ordinarily seem unspotted from the world, are afflicted with umbrella morals.

It was a well-known preacher who was found dead in a first-class railway carriage with a third-class ticket in his pocket. And as for books, who has any morals where they are concerned? I remember some years ago the library of a famous divine and literary critic, who had died, being old. It was a splendid library of rare books, chiefly concerned with seventeenth-century writers, about whom he was a distinguished authority. Multitudes of the books had the marks of libraries all over the country. He had borrowed them and never found a convenient opportunity of returning them. They clung to him like pre-cedents to law. Yet he was a holy man and preached admirable sermons, as I can bear witness. And, if you press me on the point, I shall have to own that it is hard to part with a book you have come to love.

It is possible, of course, that the gentleman who took my silk umbrella did really make a mistake. Perhaps if he knew the owner, he would return it with his compliments. After my experience to-day, I think I will engrave my name on my umbrella. But not on that baggy thing standing in the corner. I do not care who relieves me of that. It is anybody’s for the taking.

Pothuraju left home with his share. He went to a distant land, made a lot of friends and soon spent all his property lavishly on friends, food and drinks. All his friends left him.

At that time, there was a famine and Pothuraju had no work and food. None of his friends gave him food or money. He took up the job of feeding pigs. Sometimes, he had to eat the food kept for the pigs. He was very sad about his condition. He soon began to think of his father and his brother. He said to himself, “In my father’s house, even the servants have enough food. They get good shelter too. But here, I am struggling for food and shelter. I will go back to my father. 1 will beg him to take me as his servant.”
So decided, the dishonest son set out for his father’s house. In the meantime, his father was always thinking of his second son. He would sit near the windows. He would look out at the road, expecting his son to return home.

The Journey Summary in English

The Journey’ is an excellent piece of work written by Yeshe Dorjee Thongchi, a prominent Assamese writer and it is translated into English by D.P. Nath. The author was a government officer. He came to his village to get married. His parents had arranged his marriage, according to the customs of their tribal society. After spending six months at home, he was preparing to return to his place of work. But he didn’t want to leave behind his newly-wed wife. He thought of extending his leave too. But his responsibilities made him decide to go.

As theirs is a hilly terrain, without any motorable roads, the author always prefers to carry less luggage. Now, his problem was that he needed someone to carry his luggage as his education had made him avoid physical labour. Since most of the villagers were busy in the fields, he couldn’t find even one who could help him carry the trunk to the bus stop. Finally, the writer’s father told him that he would see him off at Dirang. He didn’t want to allow his old father to carry his trunk and so he protested. But his father decided to carry the chest to the bus stop. On the day of his departure, a large crowd gathered to wish him luck and the author left for Dirang at 10 : 20. His father had already left and he had to walk fast to catch up his father. He was very tired when he caught up with his father. He sat on a rock to rest for a while. His father drank all the wine given by him and resumed carrying the luggage on his back. The author followed his father. Neither of them spoke a word as if they were strangers. The author thought that it was improper for him to let his father carry the luggage. Although he wanted to tell his father that he would like to carry the trunk himself, he couldn’t do so because of his guilt, shame and pride. He felt that the whole world would laugh at him if he did so.

The author knew that his father had provided for his education. He thought that it was through him that his parents had earned admiration and respect from the villagers. He knew that he was physically useless in spite of his youth and strength. He concluded that it would be better to let his father carry the luggage and followed him silently After resting at two places for tiffin, they reached Dirang finally. They entered a tea shop and started sipping tea. His father asked him if he had a pair of old shoes. Then the author looked at his father’s bare feet and noticed that they were full of cracks. He noticed this for the first time. He offered his father money but he refused to take. Instead, he wanted the author’s old pair. So, the author gave him the hunting boots he was wearing. His father filled with satisfaction when he saw the author taking out his pair of leather shoes from the trunk. His father wanted to say something to him but the bus started moving. Finally the author realized that both their ways were different – his way was a luxurious one while his father’s was a difficult one.

I. Based on the information you gather about the persons, prepare a short biographical account of the person you like the most, emphasizing the exemplary work done by him/her and present it to the group/ whole class.
Answer:
Ms. Srivalli was born on 15th August, 1992. She came from a poor family. Her father was a musician and her mother was a teacher. She was a bright student. Unfortunately, she met with an accident when she was eleven and the doctors amputated both her legs. After two years of relentless struggle, she could go back to her school. She could walk with the help of artificial limbs and slowly run. Now, she can do anything like a normal woman. She learnt music from guru Rama Sastry and now she is a good singer and composer of songs. In spite of her disability, she has worked hard with great determination, discipline and dedication and achieved her target.

After she had met with the accident, her heart sank in sorrow. Sometimes she wanted to die. She hated God for doing this to her. She was terrified of her losing both the limbs. Her doctor Mr. Rao always encouraged her by telling her that she could walk and run normally. She tried and tried until she could walk. She didn’t give up at any stage. Srivalli always says, “The challenges in our lives are there to strengthen our convictions. They are not there to run us over.” With the help of her parents, friends . and guru, Srivalli has managed to reach such a position in her life. She has proved that anything can be done, if one tries hard. From her life, we can understand that one need not lose hope. Her life shows us that one s disability can’t prevent one from reaching one’s target. I feel that her life is a source of inspiration to every woman. She is able to do all these only because of her strong will power. Hence, I believe in will power with which one can achieve wonders in one’s life. I would like to wish all the best for her in the future.

II. You may also present this write up on the occasion of “Women’s Day” in your school.
Answer:
Our beloved headmaster, dear teachers and my fellow students!
I wish you a very good morning and welcome you all to the programme. At the outset, I would like to greet all the women a very happy ‘Women’s Day.’

As we all know that 8th March is celebrated as International Women’s Day to commemorate women’s achievements and the contributions made by them to the society This day is also known as the United Nations Day for women’s rights and international peace.

I have a great pleasure to say a few words about a great girl Mary Griffith on this occasion. Mary Griffith, a thirteen year old girl, has set national records in track and swimming. She has been studying at the Mundelein Middle School and has cerebral palsy. In spite of her disability she set her records in 2004 and 2005 at the National Junior Disability Championships. She always say that sports have given her a lot more confidence and taught her to balance her life. Though she has been suffering from cerebral palsy, she hasn’t lost her hope. With great faith and determination she has done so well and set her own records. Her efforts are inspirational to all the women.

We all wish her a great future and with this I will end my speech. I thank one and all for giving me this chance to share my views with you.

10th Class Maths 14th Lesson Statistics Ex 14.2 Textbook Questions and Answers

Question 1.
The following table shows the ages of the patients admitted in a hospital during a year:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 1
Find the mode and the mean of the data given above. Compare and interpret the two measures of central tendency.
Answer:
Maximum number of patients joined in the age group 35 – 45.
∴ Modal class is 35 – 45.
Lower limit of the modal class ‘l’ = 35
Class size h = 10
Frequency of modal class, f1 = 23
Frequency of the class preceding the modal class f0 = 21
Frequency of the class succeeding the modal class f2 = 14
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 2
∴ Mode = \(l+\frac{\left(f_{1}-f_{0}\right)}{2 f_{1}-f_{0}-f_{2}} \times h\)
\(\begin{array}{l}
=35+\left(\frac{23-21}{2 \times 23-21-14}\right) \times 10 \\
=35+\left(\frac{2}{46-35}\right) \times 10
\end{array}\)
= 35 + \(\frac{2}{11}\) × 10
= 35 + 1.81818……
= 36.8 years.
Mean x = \(\frac{\Sigma \mathrm{f}_{\mathrm{i}} \mathrm{x}_{\mathrm{i}}}{\Sigma \mathrm{f}_{\mathrm{i}}}\)
= \(\frac{2830}{80}\)
= 35.37 years.
Interpretation: Mode age is 36.8 years, Mean age = 35.37 years.
Maximum number of patients admitted in the hospital are of the age 36.8 years, while on an average the age of patients admitted to the hospital is 35.37 years. Mode is less than the Mean.

Question 2.
The following data gives the information on the observed lifetimes (in hours) of 225 electrical components:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 3
Determine the modal lifetimes of the components.
Answer:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 4
Since the maximum frequency 61 is in the class 60 – 80, this is the required modal class.
Modal class frequency, f1 = 61.
Frequency of the class preceding the modal class f0 = 52
Frequency of the class succeeding the modal class f2 = 38
Lower boundary of the modal class, l = 60
Height of the class, h = 20
∴ Mode (Z) = \(l+\frac{\left(f_{1}-f_{0}\right)}{2 f_{1}-f_{0}-f_{2}} \times h\)
\(=60+\left[\frac{61-52}{2 \times 61-(52+38)}\right] \times 20\)
= 60 + \(\frac{9}{122-90}\) × 20
= 60 + \(\frac{9}{32}\) × 20
= 60 + 5.625
= 65.625 hours.

AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 5
Answer:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 6
Since the maximum families 40 lies in the class 1500 – 2000, this is the required modal class.
Lower boundary of the modal class (l) = 1500
Frequency of the modal class (f1) = 40
Frequency of the class preceding the modal class f0 = 24
Frequency of the class succeeding the modal class f2 = 33
Height of the class, h = 500
Hence, modal monthly income = Rs. 1847.83.
Assumed mean (a) = 3250
∑fi = 200, ∑uifi = -235
Mean monthly income = \(\overline{\mathrm{x}}=\mathrm{a}+\frac{\Sigma \mathrm{f}_{\mathrm{i}} \mathrm{u}_{\mathrm{i}}}{\Sigma \mathrm{f}_{\mathrm{i}}} \times \mathrm{h}\)
= 3250 – \(\frac{235}{200}\) × 500
= 3250 – 587.5
= Rs. 2662.50

Question 4.
The following distribution gives the state-wise, teacher-student ratio in higher secondary schools of India. Find the mode and mean of this data. Interpret the two measures.
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 7
Answer:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 8
Since the maximum number of states ‘10’ lies in the class interval 30-35, this is the modal class.
Lower boundary of the modal class, l = 30
Frequency of the modal class, f1 = 10
Frequency of the class preceding the modal class = f0 = 9
Frequency of the class succeeding the modal class = f2 = 3
Height of the class, h = 5
∴ Mode (Z) = \(l+\left(\frac{\mathrm{f}_{1}-\mathrm{f}_{0}}{\left(\mathrm{f}_{1}-\mathrm{f}_{0}\right)+\left(\mathrm{f}_{1}-\mathrm{f}_{2}\right)}\right) \times \mathrm{h}\)
\(=30+\frac{10-9}{(10-9)+(10-3)} \times 5\)
= 30 + \(\frac{1×5}{1+7}\)
= 30 + \(\frac{5}{8}\)
= 30 + 0.625
= 30.625
Mean \(\overline{\mathrm{x}}=\mathrm{a}+\frac{\Sigma \mathrm{f}_{\mathrm{i}} \mathrm{u}_{\mathrm{i}}}{\Sigma \mathrm{f}_{\mathrm{i}}} \times \mathrm{h}\)
a = assumed mean = 32.5; h = height of the class = 5
∴ x = 32.5 – \(\frac{23}{35}\) × 5
= 32.5 – 3.28
= 29.22
Mean = 30.625
Mode = 29.22
Mode states have a students – teacher ratio 29.22 and on an average this ratio is 30.625.

Question 5.
The given distribution shows the number of runs scored by some top batsmen of the world in one-day international cricket matches.
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 9
Find the mode of the data.
Answer:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 10
Maximum number of batsmen are in the class 4000 – 5000.
∴ Modal class is 4000 – 5000.
Lower boundary of the modal class ‘l’ = 4000
Frequency of the modal class, f1 = 18
Frequency of the class preceding the modal class, f0 = 4
Frequency of the class succeeding the modal class, f2 = 9
Height of the class, h = 1000
Mode (Z) = \(l+\left(\frac{\mathrm{f}_{1}-\mathrm{f}_{0}}{\left(\mathrm{f}_{1}-\mathrm{f}_{0}\right)+\left(\mathrm{f}_{1}-\mathrm{f}_{2}\right)}\right) \times \mathrm{h}\)
Mode (Z) = \(4000+\frac{18-4}{(18-4)+(18-9)} \times 1000\)
= 4000 + \(\frac{14}{14+9}\) × 1000
= 4000 + \(\frac{14000}{23}\)
= 4000 + 608.695
= 4608.69
≃ 4608.7 runs

Question 6.
A student noted the number of cars passing through a spot on a road for 100 periods, each of 3 minutes, and summarised this in the table given below.
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 11
Find the mode of the data.
Answer:
AP SSC 10th Class Maths Solutions Chapter 14 Statistics Ex 14.2 12
Since the maximum frequency is 20, the modal class is 40 – 50.
Lower boundary of the modal class ‘l’ = 40
Frequency of the modal class, f1 = 20
Frequency of the class preceding the modal class, f0 = 12
Frequency of the class succeeding the modal class, f2 = 11
Height of the class, h = 10;
Mode (Z) = \(l+\left(\frac{\mathrm{f}_{1}-\mathrm{f}_{0}}{\left(\mathrm{f}_{1}-\mathrm{f}_{0}\right)+\left(\mathrm{f}_{1}-\mathrm{f}_{2}\right)}\right) \times \mathrm{h}\)
Mode (Z) = \(40+\frac{(20-12)}{(20-12)+(20-11)} \times 10\)
= 40 + \(\frac{8}{8+9}\) × 10
= 40 + \(\frac{80}{17}\)
= 40 + 4.70588
= 44.705
≃ 44.7 cars

AP State Syllabus SSC 10th Class Telugu Grammar Questions and Answers

సమాపక – అసమాపక క్రియలు

ఈ కింది వాక్యాలలోని క్రియలను గమనించండి.
1) ఉదయ్ భోజనం చేసి సినిమాకు వెళ్ళాడు.
2) వైష్ణవి పుస్తకం చదివి నిద్రపోయింది.
3) అరుణ్ చిత్రాలు గీసి ప్రదర్శనకు పెట్టాడు.

అ) సమాపక క్రియలు :
పై వాక్యాలలో ప్రతివాక్యం చివర ఉన్న వెళ్ళాడు, పెట్టాడు వంటి క్రియలు, పని పూర్తి అయ్యిందని తెలుపుతున్నాయి. వీటిని సమాపక క్రియలు అంటారు.

అసమాపక క్రియలు :
వాక్యం మధ్యలో ఉన్న ‘చేసి’, ‘గీసి’, ‘చదివి’ – అన్న క్రియలు పని పూర్తికాలేదని తెలుపుతున్నాయి. వీటిని అసమాపక క్రియలు అంటారు.

ఇ) అసమాపక క్రియా – భేదాలు
1) క్వార్ధకం : (భూతకాలిక అసమాపక క్రియ)
భాస్కర్ ఆట ఆడి, అలసిపోయి ఇంటికి వచ్చాడు. ఈ వాక్యంలో ‘భాస్కర్’ అనేది కర్త. ‘వచ్చాడు’ అనేది కర్తృ వాచకానికి చెందిన ప్రధాన క్రియ.

ఇక ఆడి, అలసి అనేవి కర్తృవాచక పదానికి చెందిన ఇతర క్రియలు. ఆడి, అలసి అనేవి క్రియలే కాని, వాటితో పూర్తి భావం తెలియడం లేదు. ఆడి, అలసిపోయి అనే క్రియల తర్వాత, “ఏమి చేస్తాడు ?” అనే ప్రశ్న వస్తోంది. ఆడి, అలసిపోయి అనే క్రియలు, భూతకాలంలోని పనిని సూచిస్తున్నాయి. వీటిని భూతకాలిక అసమాపక క్రియలనీ, ‘క్త్వార్థకం’ అని పిలుస్తారు.

ఈ క్రియలన్నీ ‘ఇ’ కారంతో అంతమవుతాయి. అంటే చివర – ‘ఇ’ అనే ప్రత్యయం చేరిన క్రియారూపం ‘క్వార్థం’.
ఉదాహరణలు :
పుష్ప అన్నం తిని నిద్రపోయింది. ఇందులో ‘తిని’ అనేది “క్వార్ధకం” (అసమాపక క్రియ).

2) శత్రర్థకం: (వర్తమాన అసమాపక క్రియ)
అఖిలేశ్ మధుకర్‌తో ‘మాట్లాడుతూ’ నడుస్తున్నాడు. ఈ వాక్యంలో ‘నడుస్తున్నాడు’ అనే ప్రధానక్రియకు, ‘మాట్లాడుతూ’ అనే ఉపక్రియ వర్తమాన కాలంలో ఉండి, అసమాపక క్రియను సూచిస్తుంది.

ఈ విధంగా ‘మాట్లాడు’ అనే ధాతువుకు ‘తూ’ అనే ప్రత్యయం చేరుతున్నది. ఇలా చేరడం వల్ల వర్తమాన అసమాపక క్రియగా మారుతుంది. వర్తమాన అసమాపక క్రియను ‘శత్రర్థకం’ అంటారు.
ఉదా :
1) జ్యోతిర్మయి కంప్యూటర్ లో ఏదో చదువుతూ ముఖ్యాంశాలు రాసుకుంది.
2) మాధవి ఆలోచిస్తూ పుస్తకం చదువుతున్నది.

గమనిక : పై వాక్యాలలో 1) చదువుతూ 2) ఆలోచిస్తూ అనేవి శత్రర్థకాలు.

3) చేదర్థకం :
(ధాతువుకు తే, ఐతే అనే ప్రత్యయాలు చేరతాయి.) కింది వాక్యం చదవండి.
“కష్టపడి పనిచేస్తే ఫలితం దానంతట అదే వస్తుంది.”

పై వాక్యంలో ప్రధాన క్రియ ‘వస్తుంది’ – ఇది ఫలితాన్ని సూచిస్తుంది. ఈ ఫలితం రావాలంటే షరతును విధించడానికి చేర్చే అసమాపక క్రియ, చేస్తే ఇది కారణం. అది కార్యం. ఈ విధంగా సంక్లిష్ట వాక్యాల్లో ప్రధాన క్రియ సూచించే పని జరగటానికి షరతును సూచించే క్రియను ‘చేదర్థకం’ అంటారు. చేత్ అర్థాన్ని ఇచ్చేది – చేదర్థకం. వీటిలో ధాతువుకు తే, ఐతే అనే ప్రత్యయాలు చేరతాయి.
ఉదా :
మొక్కలు నాటితే అవి పర్యావరణానికి మేలు చేస్తాయి.

అభ్యాసం :
ఈ కింది వాక్యంలోని అసమాపక క్రియలను రాయండి.
1) రమ రోడ్డు మీద ఉన్న ఒక కాగితం ముక్కను తీసి దగ్గరలో ఉన్న చెత్తకుండీలో వేసి మళ్ళీ సైకిలెక్కి వెళ్ళిపోయింది.
జవాబు:
తీసి, వేసి, ఎక్కి అనేవి ‘క్వార్ధకం’ అనే అసమాపక క్రియలు.

1) సూర్యుడు తూర్పున ఉదయిస్తాడు.
2) సూర్యుడు పడమట అస్తమిస్తాడు.

1) సామాన్య వాక్యం
2) సంక్లిష్ట వాక్యం
3) సంయుక్త వాక్యం

1) ఉష పాఠం చదువుతున్నది.
2) మురళి మంచి బాలుడు.

1) సామాన్య వాక్యం :
గమనిక : మొదటి వాక్యంలో క్రియ ఉంది. రెండో వాక్యంలో క్రియ లేదు. ఈ విధంగా క్రియ ఉన్నా, లేకున్నా, ఒకే ఒక్క భావాన్ని ప్రకటించే వాక్యాలను సామాన్య వాక్యాలు అంటారు.

2) సంక్లిష్ట వాక్యం :
ఈ కింది సామాన్య వాక్యాలను కలిపి రాయండి.

సామాన్య వాక్యాలు :
అ) రాజు అన్నం తిన్నాడు.
ఆ) గోపి పరీక్ష రాశాడు.
ఇ) గీత బడికి వెళ్ళింది.

గమనిక :
పై వాక్యాల్లో తిన్నాడు, రాశాడు, వెళ్ళింది అనే క్రియలు సమాపక క్రియలు. ప్రతి వాక్యంలో ఒకే సమాపక క్రియ ఉంది. ఇలా ఒకే సమాపక క్రియ ఉంటే, ఆ వాక్యాలను “సామాన్య వాక్యాలు’ అంటారు.

కొన్ని సామాన్య వాక్యాలు క్రియ లేకుండా కూడా ఉంటాయి.
ఉదా :
హైదరాబాదు మన రాష్ట్ర రాజధాని.

సామాన్య వాక్యాలు :
గీత బజారుకు వెళ్ళింది. గీత కూరగాయలు కొన్నది.

గమనిక :
పై సామాన్య వాక్యాలలో రెంటిలోనూ ‘గీత’ అనే నామవాచకం ఉంది. ఈ విధంగా తిరిగి చెప్పబడిన నామవాచకాన్ని తొలగించి, మొదటి వాక్యంలోని ‘వెళ్ళింది’ లోని క్రియను ‘వెళ్ళి’ అనే అసమాపక క్రియగా మార్చి రాస్తే సంక్లిష్ట వాక్యం ఏర్పడుతుంది.

Question 1.
A metallic sphere of radius 4.2 cm. is melted and recast into the shape of a cylinder of radius 6 cm. Find the height of the cylinder.
Answer:
Given, sphere converted into cylinder.
Hence volume of the sphere = volume of the cylinder.
Sphere:
Radius, r = 4.2 cm
Volume V = \(\frac{4}{3}\)πr3
= \(\frac{4}{3}\) × \(\frac{22}{7}\) × 4.2 × 4.2 × 4.2
= 4 × 22 × 0.2 × 4.2 × 4.2
= 4 x 22 x 0.2 x 4.2 x 4.2
= 310.464
Cylinder:
Radius, r = 6 cm
Height h = h say
Volume = πr2h
= \(\frac{22}{7}\) × 6 × 6 × h
= \(\frac{22 \times 36}{7} h\)
= \(\frac{792}{7} h\)
Hence, \(\frac{792}{7} h\) = 310.464
h = \(\frac{310.464 \times 7}{792}\) = 2.744cm
!! π can be cancelled on both sides i.e., sphere = cylinder

Question 2.
Three metallic spheres of radii 6 cm., 8 cm. and 10 cm. respectively are melted together to form a single solid sphere. Find the radius of the resulting sphere.
Answer:
Given : Radii of the three spheres r1 = 6 cm r2 = 8 cm r3 = 10 cm
These three are melted to form a single sphere.
Let the radius of the resulting sphere be ‘r’.
Then volume of the resultant sphere = sum of the volumes of the three small spheres.
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.4 2
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.4 3
∴ 1728 = (2 × 2 × 3) × (2 × 2 × 3) × (2 × 2 × 3)
r3 = 12 × 12 × 12
r3 = 123
∴ r = 12
Thus the radius of the resultant sphere = 12 cm

Question 3.
A 20 m deep well with diameter 7 m. is dug and the earth got by digging is evenly spread out to form a rectangu¬lar platform of base 22 m. × 14 m. Find the height of the platform.
Answer:
Volume of earth taken out = πr2h
= \(\frac{22}{7}\) × \(\frac{7}{2}\) × \(\frac{7}{2}\) × 20
= 770 m
Let height of plot form = H m.
∴ 22 × 14 × H = \(\frac{22}{7}\) × \(\frac{7}{2}\) × \(\frac{7}{2}\) × 20
H = \(\frac{35}{14}\) = \(\frac{5}{2}\) = \(2 \frac{1}{2} \mathrm{~m}\)
∴ The height of the plat form is \(2 \frac{1}{2} \mathrm{~m}\)

Question 4.
A well of diameter 14 m. is dug 15 m. deep. The earth taken out of it has been spread evenly all around it in the shape of a circular ring of width 7 m to form an embankment. Find the height of the embankment
Answer:
Volume of the well = Volume of the embank
Volume of the cylinder = Volume of the embank
Cylinder :
Radius r = \(\frac{d}{2}\) = \(\frac{14}{2}\) = 7 cm
Height/depth, h = 15 m
Volume V = πr2h
= \(\frac{22}{7}\) × 7 × 7 × 15
= 22 × 7 × 15
= 2310 m3
Embank:
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.4 4
Let the height of the embank = h m
Inner radius ‘r’ = Radius of well = 7 m
Outer radius, R = inner radius + width
= 7m + 7m = 14 m
Area of the base of the embank = (Area of outer circle) – (Area of inner circle)
= πR2 – πr2
= π(R2 – r2)
= \(\frac{22}{7}\)\(\left(14^{2}-7^{2}\right)\)
= \(\frac{22}{7}\) × (14+7) × (14-7)
= \(\frac{22}{7}\) × 21 × 7
= 462 m2
∴ Volume of the embank = Base area × height
= 462 × h = 462 h m3
∴ 462 h m3 = 2310 m3
h = \(\frac{2310}{462}\) = 5 m.

Question 5.
A container shaped like a right circular cylinder having diameter 12 cm. and height 15 cm. is full of ice-cream. The ice-cream is to be filled into cones of height 12 cm. and diameter 6 cm., having a hemispherical shape on the top. Find the number of such cones which can be filled with ice-cream.
Answer:
Let the number of cones that can be filled with the ice-cream be ‘n’.
Then total volume of all the cones with a hemi spherical top = Volume of the ice-cream
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.4 5
Ice-cream cone = Cone + Hemisphere = πr2h
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.4 6
Cone:
Radius = \(\frac{d}{2}\) = \(\frac{6}{2}\) = 3 cm
Height, h = 12 cm
Volume V = \(\frac{1}{3}\)πr2h
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × 3 × 3 × 12
= \(\frac{22}{7}\) × 36
= \(\frac{792}{7}\)
Hemisphere:
Radius = \(\frac{d}{2}\) = \(\frac{6}{2}\) = 3 cm
Volume V = \(\frac{2}{3}\)πr3
= \(\frac{2}{3}\) × \(\frac{22}{7}\) × 3 × 3 × 3
= \(\frac{44 \times 9}{7}\)
= \(\frac{396}{7}\)
∴ Volume of each cone with ice-cream = \(\frac{792}{7}\) + \(\frac{396}{7}\) = \(\frac{1188}{7}\) cm3
Cylinder:
Radius = \(\frac{d}{2}\) = \(\frac{12}{2}\) = 6 cm
Height, h = 15 cm
Volume V = πr2h
= \(\frac{22}{7}\) × 6 × 6 × 15
= \(\frac{22 \times 36 \times 15}{7}\)
= \(\frac{11880}{7}\)
∴ \(\frac{11880}{7}\) = n × \(\frac{11880}{7}\)
⇒ n = \(\frac{11880}{7}\) × \(\frac{7}{1188}\) = 10
∴ n = 10.

Let the number of lead shots dropped = n
Then total volume of n lead shots = \(\frac{1}{4}\) volume of the conical vessel.
Lead shots:
Radius, r = 0.5 cm
Volume V = \(\frac{4}{3}\)πr3
= \(\frac{4}{3}\) × \(\frac{22}{7}\) × 0.5 × 0.5 × 0.5
Total volume of n – shots
= n × \(\frac{4}{3}\) × \(\frac{22}{7}\) × 0.125
Cone:
Radius, r = 5 cm;
Height, h = 8 cm
Volume, V = \(\frac{1}{3}\) πr2h
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × 5 × 5 × 8
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × 200

Answer:
Volume of the iron pillar = Volume of the cylinder + Volume of the cone
Cylinder:
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 1
Radius = \(\frac{d}{2}\) = \(\frac{20}{2}\) = 10 cm
Height = 2.8 m = 280 cm
Volume = πr2h
= \(\frac{22}{7}\) × 10 × 10 × 280
= 88000 cm3
Cone:
Radius ‘r’ = \(\frac{d}{2}\) = \(\frac{20}{2}\) = 10 cm
height ‘h’ = 42 cm
Volume = \(\frac{1}{3}\)πr2h
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × 10 × 10 × 42
= 4400 cm3
∴ Total volume = 88000 + 4400 = 92400 cm3
∴ Total weight of the pillar at a weight of 7.5 g per 1 cm3 = 92400 × 7.5
= 693000 gms

Question 2.
A toy is made in the form of hemisphere surmounted by a right cone whose circular base is joined with the plane surface of the hemisphere. The radius of the base of the cone is 7 cm. and its volume is 3/2 of the hemisphere. Calculate the height of the cone and the surface area of the toy correct to 2 places of decimal.
(Take π = \(3 \frac{1}{7}\))
Answer:
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 2
Given r = 7 cm and
Volume of the cone = \(\frac{3}{2}\) volume of the hemisphere
\(\frac{1}{3}\)πr2h = \(\frac{3}{2}\) × \(\frac{2}{3}\) × πr3
∴ h = 3r
= 3 × 7 = 21 cm
Surface area of the toy = C.S.A. of the cone + C.S.A. of hemisphere
Cone:
Radius (r) = 7 cm
Height (h) = 21 cm
Slant height l = \(\sqrt{r^{2}+h^{2}}\)
= \(\sqrt{7^{2}+21^{2}}\)
= \(\sqrt{49+441}\)
= √490
= 22.135 cm.
∴ C.S.A. = πrl
= \(\frac{22}{7}\) × 7 × 22.135 = 486.990 cm2
Hemisphere:
Radius (r) = 7 cm
C.S.A. = 2πr2
= 2 × \(\frac{22}{7}\) × 7 × 7
= 308 cm2
C.S.A. of the toy = 486.990 + 308 = 794.990 cm2

AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 3
Height of the cone = edge of the cube = 7 cm
∴ Volume of the cone V = \(\frac{1}{3}\)πr2h
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × \(\frac{7}{2}\) × \(\frac{7}{2}\) × 7
= 89.83 cm3.

Question 4.
A cylindrical tub of radius 5 cm and length 9.8 cm is full of water. A solid in the form of right circular cone mounted on a hemisphere is immersed into the tub. The radius of the hemi¬sphere is 3.5 cm and height of cone outside the hemisphere is 5 cm. Find the volume of water left in the tub. (Take π = \(\frac{22}{7}\))
Answer:
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 4
The tub is in the shape of a cylinder, thus
Radius of the cylinder (r) = 5 cm
Length of the cylinder (h) = 9.8 cm
Volume of the cylinder (V) = πr2h
= \(\frac{22}{7}\) × 5 × 5 × 9.8
Volume of the tub = 770 cm3.
Radius of the hemisphere (r) = 3.5 cm
Volume of the hemisphere = \(\frac{2}{3}\)πr3
= \(\frac{2}{3}\) × \(\frac{22}{7}\) × 3.5 × 3.5 × 3.5
= \(\frac{22 \times 12.25}{3}\)
= \(\frac{269.5}{3}\)
Radius of the cone (r) = 3.5 cm
Height of the Cone (h) = 5 cm
Volume of the cone V = \(\frac{1}{3}\)πr2h
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × 3.5 × 3.5 × 5
= \(\frac{192.5}{3}\)
Volume of the solid = Volume of the hemisphere + Volume of the cone
= \(\frac{269.5}{3}\) + \(\frac{192.5}{3}\) = \(\frac{462}{3}\) = 154 cm3
Now, when the solid is immersed in the tub, it replaces the water whose volume is equal to volume of the solid itself.
Thus the volume of the water replaced = 154 cm3.
∴ Volume of the water left in the tub = Volume of the tub – Volume of the solid = 770 – 154 = 616 cm3.

Question 5.
In the adjacent figure, the height of a solid cylinder is 10 cm and diameter 7 cm. Two equal conical holes of radius 3 cm and height 4 cm are cut off as shown in the figure. Find the volume of the remaining solid.
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 5
Answer:
Volume of the remaining solid = Volume of the given solid – Total volume of the two conical holes
Radius of the given cylinder (r) = \(\frac{d}{2}\) = \(\frac{7}{2}\) = 3.5 cm
Height of the cylinder (h) = 10 cm
Volume of the cylinder (V) = πr2h
= \(\frac{22}{7}\) × 3.5 × 3.5 × 10
= \(\frac{2695}{7}\)
= 385 cm3.
Radius of each conical hole, ‘r’ = 3 cm
Height of the conical hole, h = 4 cm
Volume of each conical hole,
V = \(\frac{1}{3}\)πr2h = \(\frac{1}{3}\) × \(\frac{22}{7}\) × 3 × 3 × 4
= \(\frac{792}{21}\)
= \(\frac{264}{7}\)
Total volume of two conical holes = 2 × \(\frac{264}{7}\) = \(\frac{528}{7}\) cm3
Hence, the remaining volume of the solid

Question 6.
Spherical marbles of diameter 1.4 cm. are dropped into a cylindrical beaker of diameter 7 cm., which contains some water. Find the number of marbles that should be dropped into the beaker, so that water level rises by 5.6 cm.
Answer:
Rise in the water level is seen in cylindrical shape of Radius = Beaker radius
= \(\frac{d}{2}\) = \(\frac{7}{2}\) = 3.5 cm
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 6
Height ‘h’ of the rise = 5.6 cm.
∴ Volume of the ‘water rise’ = πr2h
= \(\frac{22}{7}\) × 3.5 × 3.5 × 5.6
= \(\frac{22 \times 12.25 \times 5.6}{7}\)
= 215.6
Volume of each marble dropped = \(\frac{4}{3}\)πr3
Where radius r = \(\frac{d}{2}\) = \(\frac{1.4}{2}\) = 0.7 cm
∴ V = \(\frac{4}{3}\) × \(\frac{22}{7}\) × 0.7 × 0.7 × 0.7
= 1.4373 cm3
∴ Volume of the ‘rise’ = Total volume of the marbles.
Let the number of marbles be ‘n’ then n × volume of each marble = volume of the rise.
n × 1.4373 = 215.6
= \(\frac{215.6}{1.4373}\)
∴ Number of marbles = 150.

Question 7.
A pen stand is made of wood in the shape of cuboid with three conical depressions to hold the pens. The dimensions of the cuboid are 15 cm by 10 cm by 3.5 cm. The radius of each of the depression is 0.5 cm and the depth is 1.4 cm. Find the volume of wood in the entire stand.
AP SSC 10th Class Maths Solutions Chapter 10 Mensuration Ex 10.3 7
Answer:
Volume of the wood in the pen stand = Volume of cuboid – Total volume of three depressions.
Length of the cuboid (l) = 15 cm
Breadth of the cuboid (b) = 10 cm
Height of the cuboid (h) = 3.5 cm
Volume of the cuboid (V) = lbh = 15 × 10 × 3.5 = 525 cm3.
Radius of each depression (r) = 0.5 cm
Height / depth (h) = 1.4 cm
Volume of each depressions V = \(\frac{1}{3}\)πr2h
= \(\frac{1}{3}\) × \(\frac{22}{7}\) × 0.5 × 0.5 × 1.4
= \(\frac{7.7}{3 \times 7}\) = \(\frac{1.1}{3}\) cm3
Total volume of the three depressions = 3 × \(\frac{1.1}{3}\)
= 1.1 cm3
∴ Volume of the wood = 525 – 1.1 = 523.9 cm3

AP SSC 10th Class Telugu Grammar Chandassu ఛందస్సు 2

గమనిక : గురువులు కాని అక్షరాలన్నీ లఘువులు

1) ఋ కారంతో కూడిన అక్షరం సంయుక్తాక్షరం కాదు. ‘ఋ’ అనేది అచ్చు. అందువల్ల అది లఘువు. దానికి ముందు అక్షరం కూడా లఘువే.
AP SSC 10th Class Telugu Grammar Chandassu ఛందస్సు 3

2) సంయుక్తాక్షరానికి ముందున్న అక్షరాన్ని ఊది పలికితేనే, అది గురువు అవుతుంది. లేకపోతే లఘువు అవుతుంది.

య, మా, తా, రా, జ, భా, న, స అనే సూత్రాన్ని కంఠస్థం చేసి, పై విధంగా ఒక చక్రం గీయండి. మీకు కావలసిన గణం పేరు గల మొదటి అక్షరం ఎక్కడ ఉందో గుర్తించండి. ఆ అక్షరాన్నుండి కుడిగా ఉన్న మూడక్షరాలలోనూ గురు లఘువులు ఏ క్రమంగా ఉన్నాయో, మీకు కావలసిన గణానికి గురు లఘువులు ఆ క్రమంలో ఉంటాయి.

ఉదా : మీకు ‘య’ గణం యొక్క గురు లఘువుల క్రమం కావాలి అనుకోండి. అపుడు ‘య’ నుండి కుడివైపుగా ‘యమాతా’ అనే మూడక్షరాలను వేరుగా వ్రాయండి.
AP SSC 10th Class Telugu Grammar Chandassu ఛందస్సు 12

ఆ) మూడక్షరాల గణముల నిర్ణయంలో మరో పద్ధతి :
AP SSC 10th Class Telugu Grammar Chandassu ఛందస్సు 13

అని వ్రాసుకొని, దానికి గురు లఘువులు గుర్తించండి. మీకు కావలసిన గణం పేరు గల అక్షరంతో, ప్రక్క రెండు అక్షరాలూ కలిపి, దానిలోని గురు లఘువులు ఎలా ఉన్నాయో గమనిస్తే, ఏ గణానికి ఏ అక్షరాలు ఉంటాయో తెలుస్తుంది.
ఉదా :
1) య గణం = యమాతా = I U U = ఆది లఘువు
2) మ గణం = మాతారా = U U U = సర్వ గురువు
3) త గణం= తారాజ = U U I = అంత్య లఘువు

5) జ గణం = జభాన = I U I = భాన మధ్య గురువు
6) భ గణం = భానస = U I I = ఆది గురువు
7) న గణం = నసల = I I I = సర్వ లఘువులు
8) లగము (లేక ‘వ’ గణం) = I U (లఘువు, గురువు)

Answer:

  1. In Latin “insula” means an Island.
  2. In 1868 Paul Langerhans of Germany working on the structure of Pancreas found Islets of Langerhans specialised cells richly supplied with blood vessel.
  3. But the function of pancreas remained unknown.
  4. Many others interested in the function of pancreas found that its removal from the body of an experimental animal would lead to the development of disease called ‘sugar diabetes’ (or) diabetes mellitus.
  5. Diabetes is a condition in which the amount of free sugar in the blood and in the urine is abnormally high.
  6. Later scientists found that when they tied the pancreatic duct that emerge from the duodenum caused the degeneration of pancreas but not Islets of Langerhans.
  7. Moreover the animal would not develop diabetes. This was really a strong evidence that the level of blood sugar is linked with the Islet cells.
  8. By 1912 workers were convinced that the Islets produced a secretion which directly liberated into the blood.
  9. Ten years later in Toronto, Banting, Best and Macleod finally succeeded in extracting insulin from degenerate animal pancreas whose ducts to the intestine had been tied.
  10. Insulin is now produced in large quantities for the treatment of human sufferers diabetes, to whom it is administered by injection into the skin.

i) Adrenal cortex: Adrenal cortex secretes two hormones i) cortisol and ii) Aldosterone
a) Cortisol regulates the protein, fat and carbohydrate metabolism.
b) Aldosterone increases the re-absorption of water and sodium in the kidney. It regulates the sodium levels in the body.

ii) Adrenal medulla: It secretes a hormone called Adrenaline at times of physical and mental stress. It is secreted in conditions like:

  1. fall in blood sugar levels
  2. When the person is injured.
  3. When exposed to cold conditions
  4. Suffering from pain

The hormone helps in facing such as situation. Therefore it is called the hormone of FIGHT or FLIGHT.

Question 7.
What is peristaltic movement? Explain the food movement in alimentary canal comparing with the experiment of moving potatoes in cycle tube.
Answer:
Peristaltic movement is the contraction and relaxation of the muscles of the digestive system. The movement of food through food pipe is known as peristaltic movement.
Food movement in alimentary canal:

  1. The walls of the food pipe secrete a slippery substance called mucus. Mucus lubricates and protects the oesophageal walls from damage.
  2. This helps the food bolus to slide down easily just as the oiled potatoes that move in the tube. Oil acts as lubricant and push the potatoes easily in the forward direction.
  3. The wall of the oesophagus is made up of two kinds of smooth muscles. The inner layer consists of circular muscles and the outer layer of longitudinal muscles.
  4. Contraction of the circular muscles results in narrowing of the oesophagus just behind the bolus.
  5. So the food is squeezed downwards.
  6. Contraction of the longitudinal muscles in front of the bolus widen the tube, this results in shortening of that particular part of the oesophagus.
  7. Contraction and relaxation of these muscles bring in wave like motion that propels the food bolus into the stomach by the action called as peristalsis.

Question 26.
What is the role of decomposers in the ecosystem? (OR)
How decomposers help in cleaning the environment?
Answer:

  1. If the decomposers are not present in an ecosystem the remains of the other organisms accumulate.
  2. Eventually the world would run out of carbon dioxide or nitrate or phosphate or other inorganisms material essential for life.
  3. The decomposers breakdown the organic waste products and dead remains of organisms into the inorganic substances needed by the producers.
  4. Most decomposition is carried out by saprophytic fungi, by bacteria and by invertebrates.

Question 5.
What is number pyramid? What does it indicate?
Answer:

  1. The number of organisms in a food chain can be represented graphically in a pyramid of number.
  2. Each bar represents the number of individuals at each tropic level in a food chain.
  3. At each link in a food chain, from the first order consumers to the large carnivores, there is normally an increase in size but decrease in number.
  4. For example in a wood, the aphids are very small and occur in astronomical numbers.
  5. The lady birds which feed on them are distinctly larger and not so numerous.
  6. The insectivorous birds which feed on the lady birds are larger still and are only present in a small number and there may only be a single pair of hawks of much larger size than the insectivorous birds on which they prey.

Question 6.
Draw the diagram of number pyramid keeping foxes as third consumers. What are the consequences if their number increases?
Answer:

  1. If the number of foxes increases, then the competition for food will be very severe and less amount of food will be available for them.
    AP SSC 10th Class Biology Important Questions Chapter 9 Our Environment 19
  2. As a result some of the foxes may not get enough food and die due to starvation.
  3. This reduces the population of foxes and very few foxes will be left in the forest.
  4. This increases the chances of survival of secondary consumers birds, hence their number increases.
  5. This increases the availability of food for foxes. Very soon a balance will be established between the number of secondary consumers and foxes.

Question 7.
What reasons are responsible for decrease in number of top carnivores and biomass starting production in a food chain?
(OR)
Why the number of organisms get decreased as we move from producers to consumer levels?
Answer:

  1. In a food chain as we move from producers to different levels of consumers the energy available will decrease gradually.
  2. Only ten percent of the energy present in one tropic level transfer to another tropic level.
  3. Biomass also decreases gradually as only 10 – 20% of the biomass is transferred from one tropic level to the next in a food chain.
  4. As there is less energy of less biomass available at top levels, number of organisms also less generally.
  5. So the number of organisms get decreased as we move from producers to different level of consumer.

AP SSC 10th Class Biology Important Questions Chapter 9 Our Environment 20

  1. The pyramid of organisms in a food chain can be represented graphically in a pyramid of number.
  2. Each bar represents the number of individuals at each tropic level in a food chain.
  3. At each link in a food chain, from the first order consumers to the large carnivores, there is normally an increase in size, but decrease in number.

Question 9.
What determines the terrestrial ecosystems on the earth?
Answer:

  1. The terrestrial ecosystems on the earth are being determined largely by the variations in climatic conditions between the poles and equator.
  2. The main climatic influences which determine these ecosystems are rainfall, temperature and availability of light from the sun.
  3. For instance, forests are usually associated with high rainfall, but the type Is influenced by temperature and light.
  4. The same applies to deserts which occur in regions where rainfall is extremely low.
  5. Thus, the climatic conditions along the horizontal climatic regions determined the terrestrial ecosystems on the earth.
  6. If we move from equatorial region to the polar region, we can come across tropical rain forests, savannah, deciduous forest, coniferous forests and then tundras respectively.
  7. Similarly altitude of the place is also a determining factor.
  8. If we climb a mountain such as Kilimanjaro in equatorial Africa, we can go through a comparable system of ecosystems, starting with tropical rain forest at the base and ending with perpetual snow and ice at the summit.

Question 10.
“All the energy in the ecosystem is ultimately derived from sunlight.” Justify.
Answer:

  1. All the organisms in an ecosystem derive energy from food.
  2. The food by its nature is the chemical energy and by in its stored form, it is the potential energy.
  3. In an ecosystem, all the consumers at any level depend upon producers for their food either directly or indirectly.
  4. The producers in any ecosystem are nothing but photosynthetic organisms such as plants, phytoplanktons and photosynthetic bacteria.
  5. Energy enters the producers in the ecosystem from the sun in the form of solar energy during photosynthesis.
  6. From the producers, the chemical energy passes to the consumers from one tropic level to the next through food.
  7. For example, in a grassland ecosystem, grass traps the solar energy and stores in its body.
  8. When this grass is eaten and assimilated by insects this stored energy enters into the body of insects.
  9. From the insects it will pass to frog, from them to snake and so on to eagle.
  10. Thus, all the energy in the ecosystem is ultimately derived from sunlight.

Question 11.
What is biological magnification? Will the levels of this magnification be different at different levels of the ecosystem?
Answer:

  1. The tendency of pollutants to concentrate as they move from one trophic level to the next trophic level is known as Biomagnification.
  2. Plants absorb pesticides, heavy metals from the soil.
  3. The primary consumers when eat these plants the remaining of pesticides and heavy metals enter their bodies.
  4. As these chemicals are not degradable, they accumulate in the bodies of organisms of all trophic levels in the food chain.
  5. Most of the plants products which we eat are grown in fields in which pesticides and fertilisers have been used.
  6. These are absorbed by the plants and cannot be removed by washing or other means.
  7. Human beings are at the top level of the food chain these chemicals get accumulated in our bodies and cause various disorders.
  8. Levels of biological magnification would increase as the trophic level increases.

AP SSC 10th Class Biology Important Questions Chapter 9 Our Environment

Question 12.
Will the impact of removing all the organisms in a trophic level be different for different trophic levels ? Can the organisms of any trophic level be removed without causing any damage to the ecosystem?
Answer:

  1. If we remove producers from ecosystem, herbivores will not survive and the entire ecosystem collapse.
  2. Removing herbivores result in increase number of producers and carnivores would not get food.
  3. Removing carnivores result in increase of herbivores to unsustainable levels.
  4. If we remove decomposers from ecosystem waste material and animal dead remains would pile up and nutrients would not be available to the producers.
  5. Some or the other damage would be caused to the ecosystem if the organisms of any trophic level is removed.
  6. However impact of removing producers or decomposers would be serve as the whole ecosystem would collapse.
  7. Without plants sun’s energy cannot be converted to chemical energy which is the basis of life on earth.
  8. Without decomposers the nutrients cannot be recycled and made available to producers.

Question 13.

Answer:

  1. Live and let live.
  2. Conserve nature – conserve life.
  3. Clean the environment, live happily.
  4. Think eco-friendly and live eco-friendly.
  5. If we protect the environment, it protect us.
  6. Reduce pollution – conserve the biodiversity.

Question 14.
Write some friendly ecosystem activities you will conduct in your school.
Answer:

  1. Forming eco-clubs: These clubs consists of student representatives from each class. They will take up the eco-friendly activities and encourage the people of that village to follow environment friendly activities.
  2. Setting up garden at school: This ensures the school and its premises green through planting of flowering plants, vegetables and fruit trees. It is a symbol of biodiversity because various plants and animals inhabit the garden.
  3. Electricity conservation programme: To save energy the school implements certain hours to be switched off habit. This switching off programme for one hour from 3.30 p.m. to 4.30 p.m. help conserve electricity in every classroom.
  4. Pollution prevention programme: A ‘no burning of trash policy should be implemented in the school. Waste materials are recycled and properly disposed to ensure a clean, waste-free environment.
  5. Making compost by organic wastes: By digging a pit at one corner of the school and throwing the organic waste particularly of mid day meal waste into pit and covering with soil layers prepares compost which can be used as manure for plants. This creates a clean environment in the school.
  6. Using cloth bags instead of polythene bags by pupil.
  7. Collection of solid waste materials and proper management of its helps in reducing soil pollution.
  8. Children should be encouraged to follow ‘3R’ system i.e. Reduce, Re use and Recycle different substances.

Question 15.
What is Ecological pyramid? Describe different types of Ecological pyramids.
Answer:

  1. The graphical representation of the feeding level structure of an ecosystem by taking the shape of a pyramid is called ecological pyramid.
    AP SSC 10th Class Biology Important Questions Chapter 9 Our Environment 9
  2. There are three types of ecological pyramids. They are
    1) Pyramid of number, 2) Pyramid of biomass and 3) Pyramid of energy.
  3. Pyramid of number is a graphical representation designed to show the number of organisms at each tropic level in a given ecosystem.
  4. The shape of this pyramid varies from ecosystem to ecosystem.
  5. In forest ecosystem the pyramid structure is partly upright and in parasitic food chain is inverted.
  6. Pyramid of biomass is a graphical representation designed to show the quantity of living matter (bio mass) at each trophic level in a given ecosystem.
  7. In terrestrial ecosystems, the biomass progressively decreases from producers to top carnivores hence the pyramid structure is upright whereas in aquatic ecosystem it is inverted.
  8. Pyramid of energy is a graphical representation designed to show the quantity of energy present at each tropic level in a given ecosystem. The pyramid of energy is always upright.
