QUESTION: 19

Five years ago the ages of Ram and Rajesh were in the ratio 1 : 10. Today the sum of their ages is 32 years. What will be their ages after 10 years?

Solution:

Let Ram’s current age be x, and Rajesh’s current age be y.
10 (x – 5) = y - 5 → 10x – 50 = y – 5 → 10x – y = 45.
x + y = 32.
On combining the above obtained equations and solving for x and y, we find that x = 7 and y = 25.
Therefore, ten years from now, their ages will be 17 and 35.

The average monthly income of a family of 4 earning members was Rs. 7500. One of the earning member died, thereby, the average became Rs. 7200. The monthly income (in rupees) of the deceased was

Solution:

Average = sum of observations/total number of observations.

Given, average monthly income of a family of 4 earning members was Rs. 7500.

∴ Sum total of the monthly income of 4 members = 7500 × 4 = Rs. 30000

Now, one of the earning member died, thereby, the average became Rs. 7200.

∴ Sum total of the monthly income of 3 members = 7200 × 3 = Rs. 21600

Monthly income of the deceased person = Rs. 30000 – Rs. 21600 = Rs. 8400

QUESTION: 65

A man spends his three months’ income in four months’ time. If the monthly income is Rs. 2,000, then what is the amount of the money he saves annually

Solution:

M = monthly income = Rs 2000

QUESTION: 66

A man walks a certain distance in certain time, if he had gone 10 km an hour faster, he would have taken 20 hours less than the scheduled time. If he had gone 15 km an hour slower, he would have been 45 hours longer on the road. The distance (in km) is

Solution:

Distance = speed × time

Let the actual speed of the man be ‘a’ km/hr and the actual time taken be ‘t’ hours.

Let the distance which he travels be d km.

Distance = speed × time

Given, a man walks a certain distance in certain time, if he had gone 10 km an hour faster, he would have taken 20 hours less than the scheduled time. If he had gone 15 km an hour slower, he would have been 45 hours longer on the road.

∴ d = a × t     ---- (1)

d = (a – 15)(t + 45)     ---- (2)

d = (a + 10)(t – 20)     ---- (3)

From (1) and (2)

45a – 15t – 675 = 0

20a – 10t + 200 = 0

Solving the above two equations, we get

a = 65 km/hr and t = 150 hours

Thus, d = a × t

⇒ d = 9750 km

4 bells ring at intervals of 30 min, 1 h,  h and 1 h 45 min respectively. All the bells ring simultaneously at 12:00 noon. They will again ring simultaneously at

Solution:

Given that the 4 bells ring at 30 min, 1 h, 1 h 30 min and 1 h 45 min. If we convert the time intervals in minutes we get the 4 bells ringing at an interval of 30 min, 60 min, 90 min and 105 min.

Now once they rang at 12:00 noon they will again ring after a time that is equal to the L.C.M of 30, 60, 90 and 105.

⇒ L.C.M of the numbers 30, 60, 90 and 105 is 1260.

Hence, they will again ring simultaneously after 1260 minutes that is equivalent to 21 hours.

∴ At 9:00 am they will again ring simultaneously.

QUESTION: 70

If x and y are positive such that x : y = 4 : 5 and x2 – y2 = -36, then the value of x - y is

Solution:

x : y = 4 : 5

Let x and y be 4a and 5a respectively.

x2 – y2 = -36

⇒ 16a2 – 25a2 = -36

⇒ a2 = 4

⇒ a = ±2

But x and y are positive.

∴ x = 8 and y = 10

⇒ x – y = -2

QUESTION: 71

A vendor purchased 40 dozen bananas for Rs. 300. Out of these 30 bananas were rotten and could not be sold. At what rate per dozen should he sell the remaining bananas to make a profit of 25%

Solution:

Given, vendor purchased 40 dozen bananas for Rs. 300.

Profit% = 25%

30 bananas were rotten.

Thus number of bananas he can sell = 40 × 12 – 30 = 450

Number of dozens he can sell = 450/12 = 37.5

Total selling price of 37.5 dozens = 300 + 25% of 300 = Rs. 375

Thus, selling price per dozen = 375/37.5 = Rs. 10

QUESTION: 76

From the four alternatives, choose the one which best expresses the meaning of the given word.

ETYMOLOGY

Solution:

The word ‘etymology’ means ‘the study of the origin of words and the way in which their meanings have changed throughout the history.’
E.g. The etymology of the word ‘cell’ is amazing.

The related synonym for this would be ‘derivation’ in linguistics term it means ‘the set of stages that link a sentence in a natural language to its underlying logical or original form’.

‘Enhance’ means ‘to intensify something or improve the quality of something’.
Eg: He worked hard to enhance his reputation.

‘Envy’ means ‘to be jealous of something’.
Eg: The girls envied her beauty.

‘Result’ means ‘the outcome or the consequence of something’.
E.g. The boy had to face the consequences for the mistakes that he committed.

Thus, option 1 is the correct one.

QUESTION: 77

From the four alternatives, choose the one which best expresses the opposite meaning of the given word.

MAGNANIMOUS

Solution:

‘Magnanimous’ means ‘being generous’. Thus, 'selfless', 'benevolent' and 'charitable' are synonyms. The only option which is opposite in meaning is ‘selfish’.

QUESTION: 78

Some parts of the sentence have errors and some are correct. Find out which part has an error and mark that part as your answer. If there are no errors, mark ‘No error’ as your answer.

They study Masters in / Computer Science from / an university in England.

Solution:

Here, even though ‘university’ begins with a vowel ‘u’, it doesn’t start with a vowel sound. Instead, it starts with the sound of a consonant ‘y’ like other similar words ‘European, youth, etc.’ Thus, the use of ‘an’ is incorrect. The correct article in the given sentence will be ‘a’. Thus, the correct option is 3.

QUESTION: 79

Some parts of the sentence have errors and some are correct. Find out which part has an error and mark that part as your answer. If there are no errors, mark ‘No error’ as your answer.

Contrary to earlier predictions, / demand for sugarcane had not / increased  in recent years.​

Solution:

‘Had not’ is incorrect here as the current year is also counted in ‘recent years’ and the action is not over. Also, the action has an impact in the present. Hence, ‘has not’ should be used. Thus, the error is in option 2.

QUESTION: 80

Some parts of the sentence have errors and some are correct. Find out which part has an error and mark that part as your answer. If there are no errors, mark ‘No error’ as your answer.

Standing / at the gate, / a scorpion stung Amit.

Solution:

As it is, the sentence reads as if the scorpion was standing at the gate. The participle or the modifier must have some noun or pronoun immediately near it as it modifies the corresponding noun. Here, ‘Amit’ must be standing at the gate and not ‘the scorpion’. The following sentence is incorrect because the Participle is left without a proper agreement of the correct subject which is ‘Amit’. We can use ‘active voice’ to show the appropriate subject immediately after the modifier. The correct sentence would read as ‘Standing at the gate, Amit was stung by a scorpion’. Thus, the correct option is 3.

QUESTION: 81

In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed choose 'No improvement'.

At this moment, he and his friends "is going to the park."

Solution:

When the two nouns in the sentence are joined by the word ‘and’ it is clear that they multiple subjects and so plural verb must follow it. Also the use of ‘at this moment’ suggests that the action is going on at the time of speaking and so present continuous tense must be used. Thus, the correct answer is 1.

QUESTION: 82

In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed choose 'No improvement'.

"As she could come", he had left and so they couldn’t meet that day.

Solution:

‘Before’ is used with past tense to denote  the period of time preceding any event. Here, as he already left and they couldn’t meet, it is obvious that he must have left before she came. Hence, the correct answer is 2.

QUESTION: 83

In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed choose 'No improvement'.

Doctors agree that factors such as cigarette smoking, eating rich foods, and alcohol consumption "not only damage by themselves but also aggravate" genetic predispositions towards certain diseases.

Solution:

Here, ‘Not only x...but also y’ is correctly used. In 1, ‘aggravating’ is incorrect as it means ‘annoying’ when used in participle form. 3 is wrong because ‘not only’ without ‘but also’ is wrong. In 1, simple present tense should have been used. Thus, the correct answer is 4.

QUESTION: 84

In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed choose ‘No improvement’.

The hunter found no "difficulty in jumping" the tiger.

QUESTION: 85

In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed choose ‘No improvement’.

Since he had parked on this side, his car was "toed" away.

Solution:

‘Toe’ is one of the digits of your foot. ‘Toil’ means to work hard. ‘Tow’ refers to an act of taking something (heavy or unwilling) away and is a verb. If a car is parked on the wrong side, the authorities will come and take the car away forcibly. So, in the context of the sentence we need to use the verb ‘tow’ and thus option 1 is the best phrase to replace in the sentence.

QUESTION: 86

Fill in the blanks with the most appropriate word out of the four alternatives suggested below each question.

As of now, the demand for Petroleum ______ increasing.

Solution:

The sentence is in present continuous tense as indicated by the usage of 'ingafter 'increase'. This means that the demand for petrol is increasing at this point of time and will continue for a while. Option 1 has the most suitable answer as the use of 'is' allows the sentence to be in present continuous form. ‘Is going to steadily’ will make the sentence grammatically incorrect. Since we are talking about recent events seen from the use of ‘now’, the past continuous (was steadily increasing) or the past perfect continuous are not appropriate (had been increasing) cannot be used here.
Hence, 1 is the correct answer.

QUESTION: 87

Fill in the blanks with the most appropriate word out of the four alternatives suggested below each question.

Solution:

When comparing degree of the quality of persons or things the word ‘than’ is normally used when we have comparative adjective like better, worse, smarter etc. Words like superior, inferior, junior, senior etc. Are not comparative adjective therefore 'to' is preferred, thus it must used to fill the blank. Thus, the correct answer is option 4.

QUESTION: 96

Directions: Read the passage given below and then answer the questions given below the passage. Some words has been highlighted. Pay careful attention.

The pitiful situation of the homeless is a problem. To estimate the number of homeless people is difficult as it would depend on who we define as being homeless since there are the street people or those who sleep in bus or railway stations, parks, roads, etc. Many of them are young runaways, who have left home voluntarily. Then there are the ones living in old age homes or shelters which are supported by government or are privately funded. Many of these used to live with their families or friends earlier. They may have families with children, whereas the people on the streets are almost always single. Many would argue that these people are alcoholics, drug users, or mentally ill, while others would say that homelessness is caused by a steeply escalating price index and stagnating or declining pay scales. One truth that shines glaringly is the need for better policies for our people so that they do not end up homeless.

Q. Why is it difficult to estimate the number of homeless people?

Solution:

According to the given passage, it is difficult to estimate the number of homeless people because the process depends on who we define as the homeless. Thus, it can be understood that since the homeless people come from different situational backgrounds and face different kind of difficulties, they cannot be categorized into one unit, thus making the process of their identification difficult. In relation to this, option 3 can be said to be the correct answer. Note that the passage mentions nothing about the large number of the homeless people being a roadblock in their identification. Option 1 and 4 are also incorrect in the context of the sentence.

Q. According to the passage, many  ______.

Solution:

The passage mentions that ‘many would argue that these people are alcoholics, drug users, or mentally ill’. Thus, according to the passage, many people think that since the homeless are out in the streets, they are mentally unstable. Thus, option 2 is the correct answer in this context. The other options are not mentioned in the passage.

QUESTION: 98

One truth that shines glaringly is the need for better policies for our people so that they do not end up homeless.

Q. What kind of distinction does the passage make between the sheltered homeless and the ones who dwell on the streets?

Solution:

The passage makes a clear distinction between the sheltered homeless dwelling in the public and privately funded shelters and the homeless who dwell on the streets. The passage also clearly mentions that many of the people living in old age homes or shelters … have families with children. On the other hand the homeless living in the streets are almost always single. Thus, option 4 is correct in the context of the passage. Note that in the other options either both or one of the data are incorrect.

QUESTION: 99

The pitiful situation of the homeless is a problem. To estimate the number of homeless people is difficult as it would depend on who we define as being homeless since there are the street people or those who sleep in bus or railway stations, parks, roads, etc. Many of them are young runaways, who have left home voluntarily.

One truth that shines glaringly is the need for better policies for our people so that they do not end up homeless.

Q. According to the passage, homelessness is caused by _______.

Solution:

Though the reasons for homelessness are varied, the passage puts forward the following argument as one of the possible reasons for homelessness: ‘homelessness is caused by a steeply escalating price index and stagnating or declining pay scales’. ‘Extravagent spending’ can lead to loss of monetary stability but becoming homeless as a consequence is a farfetched idea. Also, we cannot say that the love of open air makes people want to live in squalid and deplorable conditions. Option 2 is something which has not been stated in the passage. Thus, option 3 is the correct answer.
