PRELIMS MODEL TEST-23

ANSWER KEY AND EXPLANATION

1. Answer (b) Explanation Statement (2) can be directly inferred from the last line of the passage. “You can survive your own version of Beast Barracks, if you will resolve the same thing”.

2. Answer (b) Explanation Statement (2) can be inferred from the passage as it is directly stated in the passage that the ones who do not survive are not mentally strong and thus it implies that the ones who survive are mentally strong.

3. Answer (d) Explanation None of the statements given above follow from the passage.

4. Answer (a) Explanation Let the set of people who drank soft drinks = S and coffee = C total person attended the party = 100% those who drink coffee = 70% = n(C) those who drink soft drinks = 65% = n(S) 27% didn’t drink anything So, people who drink any one of coffee and soft drinks = 100 – 27 = 73% = n(SUC) so n(SUC) = n(S) + n(C) – n(S∩C) n(S∩C) = n(S) + n(C) - n(SUC) = 65% + 70% - 73% = 62% according to this, we can draw the venn diagram as follows.

Date: 09-06-2017

In question it is given that people who drank both = 248 which corresponds to 62% in above diagram We are required to find out total people attended the party ie 100%

Therefore, total people attended the party = 248

62 x 100 = 400 people attended the party

5. Answer (c) Explanation Actually Arjun has to make a lead of 600 m, because when Arjun will be 600m ahead of Bhishma, they will be together again. Since, they make a difference of 10 m in 1 second. so, he will create 600m difference in 60 second. OR The relative speed between them is 30 – 20 = 10m/s (relative speed is the difference because they are moving in same direction.

Here, time = circumference

relative speed =

600

10 = 60seconds

6. Answer (c) Explanation 20 litre mixture = 4 litre water (20% of mixture) + 16 litre milk (remaining 80%) A new mixture is formed by adding 5 litre of water New composition of mixture = 9 litre water + 16 litre milk (new)

∴ percentage of milk in new mixture = 16

25 × 100 = 64%

7. Answer (c) Explanation Every day of the week is repeated after 7 days Hence after 56 days, it would be Saturday again And again after 3 more days ie, after 59 days the day would be Tuesday or odd day representation for Saturday is 6 ∴ after 59 days, 59 + 6 = 65 odd days will be there

Ie,65

7 => remainder is 2 ie the day will be Tuesday.

8. Answer (d) Explanation The author even gives us examples of how liberal education equips people to make better choice in choosing their dentists or hobbies. From the line ‘..ability of the man of disciplined mind to direct this power effectively upon problems for which he has not specifically trained is proved by examples without number..’ we can choose option (D) as the answer.

9. Answer (a) Explanation The author is giving attention to how liberal education makes us better at facing challenge.

10. Answer (c) Explanation It is a direct question the answer to which can be taken from the following line ‘.even a successful company appoints an outsider who can introduce some particular expertise..’

11. Answer (d) Explanation The passage deals with the planning of an organization. None of the options other than option (d) are related to the passage. They are irrelevant and not even mentioned in the passage.

12. Answer (b)

Explanation

According to P % Q + R – S, we can draw the position of P, Q, R, S like this

So, S is in the South-East of Q.

13. Answer (d)

Explanation

The height of the lighthouse, the distance from the base of the lighthouse to the ship and the distance from the top of

the lighthouse to the ship forms a right triangle. So we can find the 3rd side of the right triangle if two sides are given.

Let the distance from base of lighthouse to ship be x.

Then, 𝑥2 + 912 = 1092

𝑥2 = 1092 - 912

= 11881 – 8281 = 3600

Therefore, x = √3600 = 60m

14. Answer (c)

Explanation

by looking at the graph itself and without going for any calculation, we can answer the question.

All products other than shampoo has got an increase of nearly 100% or more from the year 1995 to 2000. So your

answer must be shampoo.

Otherwise, percentage of increase in sale can be solved like this

Lipsticks = [ (48.17−20.15)

20.15 x 100] % = 139.06%

Nail Enamels = [ (37.76−5.93)

5.93 x 100]% = 536.76%

Shampoos = [ (12.21−7.88)

7.88 x 100]% = 54.95%

Conditioners = [(10.19−5.01)

5.01 x 100]% = 103.39%

Talcum powder = [(29.14−14.97)

14.97 x 100]% = 94.65%

15. Answer (b)

Explanation

increase in percentage sale of each products is

Lipsticks => 139.06%

Nail Enamels => 536.76%

Shampoos => 54.95%

Conditioners = > 103.39%

Talcum powder => 94.65%

Therefore the maximum increase is for nail enamels.

16. Answer (c) Explanation In this case, you need to understand the primary purpose of the paragraph. The paragraph provides details about the courtship behaviour of Jackdaws. The author says this is parallel with that of humans. He is comparing a single aspect of male human and male Jackdaw behaviour. This helps us identify option (C) as the correct answer.

17. Answer (d) Explanation The whole passage is about how a male bird tries to woo a female bird. So, the meaning of courtship can be understood. Had the question asked ‘Jackdaw's courtship behaviour’, the answer would have been option (b), but here it just asks ‘courtship behaviour’ so the correct option in this case is option (d).

18. Answer (d) Explanation As given in the passage, these people were killed on suspicion that they were trying to smuggle copper from North Korea to China. Since it was a mere suspicion and not a confirmed fact, the answer is option D.

19. Answer (b) Explanation The answer can be found in the lines: ‘Recent months have seen some signs of discord between the long-term allies…’. The word ‘ally’ means one party in helpful association with another which means China and Korea have been long term partners. So we need a positive word here. Antagonistic and Belligerent both mean hostile and adversarial. Apathetic means without concern. So the answer is Option B.

20. Answer (c)

Explanation

The letters at the odd positions are moved two steps backward and the letters at even positions

are moved two steps forward to get the value.

Ie

(T) – 2 = R

(O) + 2 = Q

(G) – 2 = E

(E) + 2 = G

(T) – 2 = R

(H) + 2 = J

(E) – 2 = C

(R) + 2 = T

Like that the code for PAROLE will be NCPQJG

21. Answer (c)

Explanation

Speed of boy 1 = 5 kmph

Speed of boy 2 = 5.5 kmph

Since they are moving in same direction,

Their relative speed = 5.5 – 5 = 0.5kmph

Now we need to find the time taken by boy 2 to cover extra 8.5km when compared with boy 1

So distance = 8.5 km

∴ time taken = distance to cover

relative speed =

8.5

0.5 = 17hours

22. Answer (d)

We know that, to be in the form that the number of rows and the number of columns to be equal the number should

be a perfect square ( ).

Given number is 1200

The perfect number which is above and near to 1200 is 1225 which is 35 35.

The minimum number of coins he need is 25.

23. Answer (a)

Explanation

According to the meaning of different sign given in the question,

24 - 4 ÷ 6 x 3 + 4 could be rewritten as 24 ÷ 4 + 6 - 3 x 4

So the result will be

6 + 6 - 12 = 0

24. Answer (d)

Explanation

Consider the first row of the figure

3 + 11 – 9 = 5

9 + 2 – 1 = 10

5 + 6 – x = 4

Therefore x = 7

25. Answer (a) Explanation The answer can be found in first two lines of the passage. Robots may wear the halo of high technology, as per the popular opinion but they came into being to meet a rather mundane need – that is to replace humans in work which required repetitive, boring and mundane tasks.

26. Answer (a) Explanation The answer can be found in lines: “the need to provide an automated environment has so far restricted robot use to large scale industry businesses’’.

27. Answer (c) Explanation According to the passage, robots can only work in an automated environment that guarantees predictability and have limited number of applications. So the answer is option C); the other options are factually incorrect.

28. Answer (b)

Explanation

If a cube is divided in to {1

𝑛}th of its original side after get painted all the sides.

Then, cubes with 1 side painted = 6 x (n – 2)2

here n = 4

∴ required number of cubes = 6 x (4 – 2)2

= 6 x 4 = 24

So, number of cubes with only one side painted is 24

29. Answer (c)

Explanation

given, A is the tallest among the four. So, A is male, D is also male, as D is the brother of B. Hence, B and C are

females; D is the husband of C. D is shorter than A and is taller than his wife C. It is given that C is taller than B. Thus,

B is the shortest.

So. Only option (c) is incorrect

30. Answer (d)

Explanation

To get the answer, draw the shape as a whole and then rotate the image. You will see that the only answer you can

obtain is answer D

31. Answer (d)

Explanation

Area to be painted is in the form of a triangle.

The area of the triangle = ½ (length of the base * height of the triangle)

As the length of the base and the height of the triangle is the same in all the three cases, the area of the

triangle formed will be the same in all the three cases, i.e. in case of triangles APB, AQB and ARB.

32. Answer (b)

15

Hence, the people at the dinner were not French = 7

15

33. Answer (b) Explanation Refer to the last sentence of the first paragraph. Option (b) is clearly the answer. In the context of the rotting of 20 million tones of grains, loco-parentis is inappropriate. Similarly, the preservation of the adivasi lifestyle is also not related to the quoted portion. So, option (a) and (d) can be eliminated. Moreover, option (c) is also incorrect as corruption is not the core issue being addressed but is identified as a consequence of the “plethora” of polices.

34. Answer (a) Explanation Option (b) is talking about an example rather than the main idea. Options (c) and (d) do not make the context of poverty or poverty line clear. Thus, only option (a) summarizes the passage in the best manner.

35. Answer (c) Explanation From the passage it is not clear whether Readyville and Woodbury were ‘closed’ connected or not. Also, based on the information available in the passage it cannot be said whether Readyville and Woodboury were in the same state or were army logistics facility. Based on the second sentence of the passage on can say that Readyville and Woodbury were both army outposts.

36. Answer (b) Explanation The passage tells us that Major Seidel commanded a squadron of Federal horse. It does not mean that major Seidel was the head of the army. Also no information is available in the passage which tells us that the fought dangerous battles or was a secretive personality. The sentence “One night a... and skilful officer” tells us that Major Seidel was a brave officer. Several thousand officials from 194 countries gathered in Cancun, Mexico, for yet another global climate summit. Dissatisfied with the pace of climate diplomacy, many individuals are now wondering what they can do about climate change on their own.

37. Answer (d)

Explanation

According to the given information, the possible distribution is

C----- D----- E----- B----- A

Where C gets highest amount of money and A gets the least amount

Difference between C and D is 5 rupee

Difference between D and B is 3 rupee and

Difference between B and A is 1 rupee.

Now, amount received by E is neither greater than D nor lesser than B

That means, either amount of E should be

1. equal to D,

2. equal to B (ie less than D by 3),

3. less than D by 2 rupee, or

4. less than D by 1 rupee

out of the four possibilities said above, 3 is given as option a), b) and c)

so the answer is (d) option any of the above is correct.

38. Answer (a)

Explanation

If the speed he is going to office is ‘S’

Then the speed he is returning from his office is ‘3S’

It is given that average speed for the whole trip is 12kmph

Average speed for a journey if the distance covered is same for different speed is = 2UV

U+V = 12

2 x S x 3S

S+3S = 12

Solving above, 6S

4 = 12, ie, S = 8kmph

39. Answer (c)

Explanation

let the son’s age in 1930 be x yr, then father’s age in 1930 be 8x yr.

now, in 1938, father’s age = (8x + 8)yr

according to the question, 8x + 8 = 10x

2x = 8 which gives x = 4

Now, son’s age in 1930 = 4yr

Therefore age of son in 1940 = 4 + 10 = 14yr

And age of father in 1940 = 8 x 4 + 10 = 32 + 10 = 42yr

Hence, the ages of son and father in 1940 will be 14yr and 42yr respectively

40. Answer (b)

41. Answer (d)

42. Answer (c)

43. Answer (b) Explanation Para 2 ends with the author wondering if it is really true and the answer is in the next para—the per capita annual energy consumption has not decreased despite many household appliances becoming 40% or 50% energy efficient.

44. Answer (c) Explanation The passage begins with global warming and individual efforts to reduce consumption. It goes on to show that energy efficiency does not reduce consumption. Hence (1) and (2) can be inferred from the passage.

45. Answer (b) Explanation Lines 1 and 2 say “Television might be abused and then it many warp the minds of its viewers…”

46. Answer (a) Explanation Line 8 says “…to enable them to cost off superstition to emancipate their minds for any kind of narrowness and…Every kind of false idea which has taken lodgment in…Minds of the people” This sentence supports this answer.

47. Answer (c)

Explanation

Let total number of men = 100

Then,

80 men are less than or equal to 50 years old (Since 80% of the men are less than or equal to 50 years old)

20 men are above 50 years old (Since we assumed total number of men as 100)

20% of the men above the age of 50 play football

Number of men above the age of 50 who play football = 20 x 20

100 = 4

Number of men who play football = 20 (Since 20% of all men play football)

Percentage of men who play football above the age of 50 = 4

20 x 100 = 20%

∴ Percentage of football players less than or equal to the age 50 = 100% - 20% = 80%

48. Answer (d)

Explanation

looking across, the long line is moving 45° clockwise at each stage and the small line is rotating 45° anti-clockwise.

50. Answer (a)

Explanation

Option (a) is the correct answer as this specifically mentions that the government is justified in banning anything that

is bad for health. Hence, it provides legitimacy to the actions of government.

Option (b) is wrong as this provides for an extra factual information for government to take necessary

action but is not a precondition for the government to take action.

Option (c) is not a conclusion as it is the real reason for thinking about soft drinking ban.

51. Answer (c)

52. Answer (d)

53. Answer (d)

54. Answer (a) Explanation The first line of the passage underlines this saying that ‘men and women’ should be treated primarily as people…….

55. Answer (d) Explanation This has been expressed by the another through the entire passage.

56. Answer (b) Explanation Line 3 mentions this term. It is followed by the word ‘this habit’. This is further explained by the subsequent lines which say once it becomes a habit it then “becomes a part of their…They become a addicted to…”

57. Answer (c) Explanation Line 9 introduces another concept and category of people who get affected by smoking other than the smokers. It is called ‘passive smoking’ and ‘non smokers’ respectively. Joining these two ideas we arrive option (c).

58. Answer (b)

59. Answer (b)

Explanation

The possible sides of the rectangle with area 15 = 1 x 15 and 3 x 5

The possible sides of the rectangle with area 48 are 1 x 48 & 2 x 24 & 3 x 16 & 4 x 12 & 6 x 8

For getting equal sides for the outer square, the only possibilities are 3,5 for first rectangle and 6,8 for the second.

These dimensions suite the requirement. (observe that 3 + 8 = 5 + 6 = 11, which is the side of the outer square)

So the answer is (b) option.

60. Answer (c)

Explanation

If the government erect the lamppost at points 2 and 4, then it can light all the road segments. So (c)

Is the answer.

61. Answer (c)

Explanation

n (A) = 34, n (B) = 42, n (A ∩ B) = 20.

So, n (A U B) = n (A) + n(B) – n(A ∩B) = 34 + 42 - 20 = 56.

Percentage failed in either or both the subjects = 56.

Hence, percentage passed = (100 - 56)% = 44%.

62. Answer (c)

Explanation

In these question, two rankings; one related with height and another with the figure of persons are given. On the basis

of the given information, these are ranked in descending order as below:

Height B ---- C ---- A ---- E ---- D

Figure B ---- A ---- D ---- C ---- E

Here, C is taller than A and E and thinner than remaining two ie, B and D.

63. Answer (c) Explanation According to the last lines of the second paragraph, it is stated that Munshi and Nehru were opposed to the arguments put forth by Tagore and Gandhi. The latter were in favor of using mother tongues as a medium of education. Since the paragraph discusses the use of English and also refers to Munshi and Tagore as Anglophiles, it can be inferred that their argument against Tagore and Gandhi was in favor of the use of English as a medium of education. Option (c) is the correct answer. Option (a) can be ruled out because it is too general. Option (b) is incorrect as there is no information to suggest that Munshi and Nehru knew that Tagore and Gandhi would lose their arguments. Option (d) is also incorrect because there is no factual information or data to suggest this inference.

64. Answer (d) Explanation Refer to the last paragraph where the author starts by pointing out that India’s elite is trained to use a foreign language (English) and their mother tongue (Hindi taken as a generalization). It is also stated “India middle class does not own any language properly”. The dictionary meaning of liminal itself is “relating to the point (or threshold) beyond which a sensation becomes too faint to be experienced”. Option (d) is the correct answer. Option (a) can be ruled out because there is no indication that India’s elite don’t have a grasp on language in general. Option (b) is incorrect because there is no suggestion that Indians use language to their advantage. Option (c) is also incorrect because evidence in the passage seems to suggest that Indians (specially the Indian middle class) are not proficient in English.

65. Answer (b)

Explanation

total number of candidates for the exam is 100%

let the set for physics = P and maths = M

percentage of candidates who took physics = 65.8% = n(P)

percentage of candidates who took mathematics = 59.2% = n(M)

total candidates = 100% = n(PUM)

n(PUM) = n(P) + n(M) – n(P∩M)

100% = 65.8% + 59.2% - n(P∩M)

n(P∩M) = (65.8% + 59.2%) - 100% = 25%

total number of students for exam is 2000 ie 100%

no. of candidates who took both physics and mathematics = 2000

100 x 25 = 500

66. Answer (a)

Explanation

It is given that the ratio of the number of students of Delhi Public School and Central School is 7:5.

So, we can assume that number of students of Delhi Public School and Central School who were

supposed to participate be 7x and 5x respectively

Two students of Delhi Public School did not turn up.

Therefore, the number of students of Delhi Public School who actually participated = 7x – 2.

Now, the ratio of students of Central School and Delhi Public School = 5x : (7x – 2 )

For, x = 1, the ratio turns out to be 5:5 = 1:1

Hence, option (a) is the correct answer.

67. Answer (d)

Explanation

Let the son's present age be x years

Then his father’s age at the time of his birth = (38 – x), which is again = x(son’s present age)

∴ (38 - x) = x x= 19yrs

So, son's age 5 years back = (19 - 5) = 14 years

68. Answer (a)

Explanation

A : B : C

Ratio of efficiency = 3 : 1 : 2

Ratio of No. of days = : :

or 2 : 6 : 3

Hence A is correct.

69. Answer (b)

Explanation

We need to find the HCF of the two lengths in order to find the largest size of the tile which could be used to pave the

rectangular plot.

3.78 meters = 378 cm = 2 × 3 × 3 × 3 × 7

5.25 meters = 525 cm = 5 × 5 × 3 × 7

Here, common factors are 3 and 7

Hence HCF = 3 × 7 = 21

Hence largest size of square tiles that can be paved exactly with square tiles is 21 cm.

70. Answer (c)

Explanation

according to the given information, the arrangement is as shown below

Priti > Rahul

Yamuna = Divya

Manju > Lokita

Rahul > Yamuna

Divya > Manju

So, the final order is as follows

Priti > Rahul > Yamuna = Divya > Manju > Lokita

So lokita got the lowest score.

71. Answer (d)

Explanation

Let X drank t cups of tea and c cups of coffee.

5t + 8c = 47, where t and c have to be some natural numbers.

Only way this is possible is when t = 3.

5(3) + 8c = 47

8c = 47 - 15 = 32

c = 4

He drank 3 cups of tea and 4 cups of coffee.

Thus he drank more coffee than tea.

72. Answer (d) Explanation Refer to the first two lines in the second paragraph of the passage. The author states that intelligence is not just about cutting-edge information but also highly polished analysis of situations. Statement (1) can be ruled out because it refers to the comprehensive understanding on information systems- this option finds no reference in the passage and

is not within its scope. Statement (2) is incorrect because it makes a reference to the requirements of good intelligence -this is beyond the scope of the passage. Option (d) is the answer.

73. Answer (c) Explanation According to the last sentence of the second paragraph. Indian agencies are blamed for misreading/misinterpreting the situation in Nepal. Option (c) is the answer. Option (a) can be ruled out because it generalizes the statement made in the passage and there is not enough information to infer this option. Option (b) goes against the information in the passage. Option (d) is incorrect as it indicates that Indian agencies have a tendency to get blamed for misreading the situation in Nepal-this is certainly not indicated by the information in the passage.

74. Answer (a) Explanation The last paragraph of the passage has two points that are established by the author—these are reflected in statement (1) and (2). Statement (3) can be ruled out because it cannot be inferred that all intelligence inputs come from sources that can’t be verified. Statement (4) is also incorrect as it makes a reference to all intelligence agencies. It also cannot be inferred that the author points to the practice mentioned in statement (4) as an unnecessary one.

75. Answer (d) Explanation The first paragraph makes a reference to the unreliable nature of terror threats issued by Indian agencies and foreign agencies. He ends by questioning the reliability of American agencies. However, in the context of the entire passage, it is clear that the author is concerned about the validity of the threats issued by the agencies. Option (a) is incorrect because it is a partial answer and does not take the entire paragraph into account. Option (b) is incorrect as it changes the meaning of the information in the passage—the option seems to indicate that there is a need to ensure that real and valid terror threats exist. Option (c) can also be ruled out because it indicates that the author favors the need for valid terror threats—this is also against the central theme of the passage.

76. Answer (c)

Total students failed in half yearly exam in D

total students in section D x 100 =

40

105 x 100 = 38%

From the above table it is clear that the failure rate is minimum for section A

80. Answer (d)

Explanation let A = his average after the 17th inning

then, (A – 3) = his average before the 17th (ie, after 16th inning)

∴ average after 17th inning = total score after 17 innings

total number of innings =

16∗ (A−3 )+85

17 = A

Ie, 17A = 16 (A – 3) + 85

17A = 16A - 48 + 85

17A – 16A = 37

Ie, average after 17th innings = A = 37
