CSAT Test-1 held on 15th

Feb. 2015 ANSWERS WITH EXPLANATION

Q. Ans. Explanation

1 A The focus of the author is towards advocating the utility of narrative literature over traditional ethical training methods-hence A. Option B is wrong because the second paragraph states that traditional training is valuable-it may not contribute much to ethical development but cannot be said to impair students sensitivity. Option C is wrong because it cannot be ascertained whether such training is becoming increasingly popular. Option D is wrong because the last paragraph states that all moral principles do not have to be relinquished.

2 C Statement 1 follows from the author stating that one must be able to adopt others points of view and engage with the story not as ones own. Statement 2 is wrong because the author does not mention a need to align with one side or another. Statement 3 is directly stated in the last sentence of the third paragraph.

3 D Statement 1 is wrong because it cannot be ascertained whether heavy coursework prevents

students from giving adequate emphasis to medical ethics. Statement 3 is wrong because the author states that abstract, philosophical training is valuable; also, he speaks about supplementing, not replacing such training.

4 D Refer to the last sentence of the second paragraph- this is a shortcoming of traditional approaches and is overcome by using narrative literature.

5 C Statement 1 is wrong because the author does not give any such suggestions that are addressed to medical schools. Statement 2 is wrong because the author does not say that current methods are counterproductive- he merely states that they have limitations that can be overcome by supplementing them with narrative literature.

6 B An Indian is known by his nationality, rather than his religion-hence, Statement 1 is wrong. Indians have adopted new cultures but it cannot be established if it was easy or difficult to do so.

2



The last three sentences support the notion that regardless of their religion, Indians are considered as belonging to one common national identity-hence, Statement 3 is correct.

7 C Statement 1 contradicts the very first sentence of the passage and is hence wrong. Statement 2 follows from the second-last sentence. Statement 3 is supported by the fact that modern developments produce uniformity and that the idea of a modern nation has more importance now.

8 D

9 B Y-x = 490 Y = 490 + x ........(i) 17x + 10 = Y.......(ii) So 17x + 10 = 490 + x 16x = 480 X = 30

10 C L.C.M. of 6, 8, 10 is 120 seconds = 2mins = 120 mins 2 mins = 60 times

11 D Y = 55x + 29 So on dividing 55x + 29 by 11 we will always get 7 as remainder. Alternate solution Let number is 84(on dividing by 55 gives remainder 29), if we will divide 84 by 11 we will get 7 as remainder.

12 C 30 10 +30 (10)

100 % =

17%

13 C ....

..100%

= 2520

20100% = 25%

14 C 1st Jan 2007 Saturday. 1st Jan 2012 Friday ( From 2007 to 2012 gap of 5 years with one leap year means 6 odd days) The 31st December 2011 would be Thursday.

15 B Pattern is: 6 2 = 12 12 3 = 36 36 4 = 144 144 5 = 720 720 6 = 4320

16 D In 1st view face no. 6 is having 1 adjacent to it and in 2nd view 5 and 3 are adjacent to 6 so with elimination technique 2 is the answer.

17 D The use of the word always makes the Statement 1 incorrect while the use of the word must makes Statement 4 incorrect. Statements 2 and 3 cannot be ascertained from the passage.

18 C Option A is wrong because the author does not provide any examples. Option B is wrong because the author does not accuse employers; in fact, he even explains how employer provided group insurance plans benefit some consumers. Option D is wrong because the causes of adverse selection are explained in

3



the first paragraph. The author mentions greed and discrimination to point out an alternate explanation for the same result. Option C is correct because some people believe that greed and discrimination are the reason behind elderly people facing difficulties in obtaining fairly priced insurance.. The author disputes this belief by stating that such people are ignoring the reality of adverse selection.

19 B Option A is wrong because the author does not advocate on behalf of consumers, but explains a situation faced by both consumers and insurance companies. Option C is wrong because it cannot be ascertained if the information presented is recently discovered. Option D is wrong because the passage does not assert that the situation discussed is morally wrong"; rather, it just explains why the situation occurs. Option B is correct because the first paragraph defines adverse selection and explains that the situation is considered a market failure; the second paragraph explains how adverse selection affects one segment of the population.

20 D Statement 1 is correct but the others are not. Statement 1 is correct

because the author explains that healthy consumers incur lower-than-average health-care costs, while consumers in poor health incur higher-than-average costs. Statement 2 is wrong because the passage does not compare the cost of health-care for full-time workers with that for any other segment of the population. Statement 3 is wrong because although the passage mentions that some consumers have difficulty finding fairly priced insurance, the passage does not assert that the cost of health-care itself is unfair. Statements 4 and 5 are not mentioned in or supported by the passage.

21 A Option B emphasizes only damage to the atmosphere; the passage encompasses more than that. Option C does not mention the atmosphere, which is the main focus of the passage. Option D is wrong because the atmosphere is an important but one example of the complex events that keeps the earth alive.

22 B The biosphere, as defined in the first paragraph, is a region (or part) of the earth; it is not the envelope around the earth, the living things on Earth, or the circulation of the

4



atmosphere.

23 D All the statements are factually correct and directly stated in the passage. But only Statement 4 answers the question that is being asked- it explains that explains that conditions would be inhospitable at the equator and poles without the circulation of the atmosphere.

24 B The second paragraph describes how variations in the strength with which solar radiation strikes the earth affects temperature. None of the other statements is discussed in terms of all temperature changes on Earth.

25 D There is no mention in the first paragraph of any reviving or cleansing effect the atmosphere may have. However, the first two sentences mention how the atmosphere protects the earth from harmful forces, hence supporting Statement 1.

26 B L.C.M. of 5, 6, 8 and 9 is 360. 707 + X = 360K So smallest possible number is 13.

27 D H.C.F. of 29.7 and 36.3 is 3.3 meters.

28 B From 10th Dec to 10th Feb we are having 6 odd days and from 10th Feb to 12th Feb 2 more odd days so total 8 odd days means 1 complete week and 1 odd day. So answer is Monday

+1 = Tuesday.

29 B

13+Parmod+4+Ghanshyam+ 5= 24.

30 A Series of squares and only 64 out of above numbers is cube as well)

31 A

32 D Manjeet -2 Is -9 An -6 IAS-8 Scoring- 5 Female- 3 Exam/Difficult- 4/7

33 C First figure:

24 + 36 + 20 + 44 = 31 4 Similarly second figure is = 27 + 25 + 20 + 8 = 20 4

34 D

35 A Let third number is 100 Then first and second number will be 80 and 50 respectively 80

50 100% = 80 is 160%

of 50

36 B B

37 D D

38 C Statement 1 will hold true only when there is danger or inward strife. Statement 2 is wrong because the absence of leaders is offset by unison among the people- it does not necessarily have an impact on the development of political democracy. Statement 3 is correct

5



because in the absence of personal eminence, the people display an intelligent readiness to lend a hand and to work in unison. Hence C.

39 A A primitive social democracy is itself a representative democracy, hence Statement 3 is wrong. There is no mention of a constitutional democracy, hence Statement 4 is wrong.

40 B Statement 1 is wrong because the need to avoid internal strife leads to a rudimentary monarchy-only when the leaders in such a system seem lacking in genuineness or representativeness does a political democracy emerge. Hence, only Statement 2 is correct.

41 C Options A and D refer to features that were found in a social democracy, not a political democracy. Option B is wrong because the last sentence of the second paragraph states that the people can merely request an amendment, not impose a radical measure.

42 A Statement 2 refers to a situation that arises after a formal system of govt. has been adopted. Statement 3 refers to problems that are faced in a political democracy.

43 C Options A, B and D cannot be ascertained from the

passage.

44 C Statement 1 follows from the second sentence while Statement 2 follows from the first and third sentence.

45 B Statement 1 is wrong because mankind has survived despite such weapons, not because of them. Statement 2 is factually correct and is further justified by the use of the word paradoxical.

46 B Rahul : Sanjeev Efficiency 100% : 125% 4 : 5 Time 5 : 4 30 days : 24 Days

47 A MN%S+T

48 D Perimeter of the figure = Sum of the circumferences of both the semi-circles + length AB + length CD = 10 + 10 + 10 + 10 = 20 + 20 = 20 ( + 1).

49 C Distance = speed x time = 330 x 10 = 3300 m (To convert m into km divide by 1000) = 3.3 km

50 C It cant be determined as total number of boys and girls who appeared in the paper is not given.

51 C Let the consecutive even numbers be x, x+2, x+4, x+6. = x + x+2 +x+4 + x+6 = 45 4 = 4x + 12 = 180 =4x = 180 12 = 168 = x = 42

6



Thus A = 42 and C = 42+2+2 = 46 And product of A and C is = 42 x 46 = 1932

52 C 16a + 16b = 48 16 (a+b) = 48 = a+b = 48/16 = a+b = 3 Now average of a and b = = a + b = 3/2 2 Therefore, average of a+b = 1.5

53 D The direction of village D cannot be found as village Ds position is not fixed with respect to village B.

54 B 1 ( 2 + 2) 15 5 = 1 (2+6) 15 = 1 8/15 = 7/15

55 C Total words Mr. Rakesh is to type = 100x 300 = 30000 words The time required to type these words = 30000/45 minutes Thus, the time at which he starts typing = 19 hours 10/9 hours = 7:53 A.M.

56 A Option B is wrong because the passage does not explain how economists draw conclusions-it only explains what the indicators relate to. Option C is too narrow to be the primary purpose-it is restricted to the last paragraph alone.

Option D is wrong because the author provides a comparison between the utility of the 3 indicators-he does not argue for their continued usage.

57 D The third paragraph states that mortgage applications and profit margins are examples of leading indicators, which have the greatest predictive power; hence D. Options A and C relate to coincident indicators which do not have significant predictive power; Option B mentions bankruptcies, which are not mentioned in the passage.

58 A The last paragraph states that "establishing a solid framework for under-standing these indicators helps economists to avoid miscalculations and to guide the country through periods of slow or negative economic growth". Hence A. Options B and D are not mentioned in the passage. Option C is wrong because it focuses only on downturns whereas the indicators are used for either upward or downward economic change.

59 D Lagging indicators have no predictive power-they serve simply as confirmation of the recent state of the economy. Therefore, lagging indicators would not be helpful in determining future courses of action.

7



Only Statement 2 requires prediction, since it adopts a futuristic orientation. The other statements are all an exercise in reviewing past actions/events.

60 B Statement 1 does not hold in the case of artistic greatness, hence is wrong. Similarly, since artistic greatness does not need subsequent proving, it is unfair to delay its recognition till the persons demise-hence, Statement 2 is correct.

61 A Statement 1 is correct because greatness in the physical sciences must be tested over time. Statement 2 is not supported by the passage since there is no mention of any such comparison.

62 D

63 D

64 B Here, circumference of circular wire = Perimeter of rectangular wire Therefore, Circumference = 2 r = 2 x 22/7 x 42 = 264 cm Perimeter = 264 cm Let the length of rectangular wire be 6x and its breadth be 5x = Perimeter = 2(l + b) = 2 (6x + 5x) = 264 = 11x = 264/2 = 132 = x = 132/11 = 12 The smaller side = 5x = 5 x 12 = 60 cm.

65 B Let the distance he covers by Car is x km

Therefore, he walks back to the original position, i.e. distance he walks back = x km Now, we know that Time = Distance/Speed = x/12 + x/3 = 5 = x + 4 x = 5 12 = 5x/12 = 5

x = 12 km

66 C Number of students who failed in at least two subjects = 100 + 140 + 50 + 70 = 360 % of students who failed in at least two subjects = 360/5000 x 100 = 7.2%.

67 C

68 D

69 D Lowest average rainfall for 5 months = 1.5 + 0.5 + 0 + 0 + 2.0

5 = 4.0 5 = 0.8

70 C Total number of cards required = n x (n-1) Where n is number of Probationers = n x (n-1) = 6320 = n2 n 6320 = 0 = n2 80n + 79n 6320 = 0 = n(n-80n) + 79 (n-80) = 0 = (n+79) (n-80) = 0 = n = 80 Thus, number of probationers = 80.

71 C Let the C.P. of pure milk x C.P. of water = Rs.100

8



Now S.P. = 100 Profit = 25% C.P. = (100 x S.P. )

100+P% = C.P. = 100 x 100

125 = 80 He has purchased 80 litres of milk and added 20 litres of water in it. i.e. in the ratio of 4:1 Thus the pure milk is 40 litres to add 10 litres of water.

72 D Kundan = 3 + Sonu Pinky = Gaurav 2 Pankaj = Pintu 6 Sonu = Pankaj + 2 Pintu = Pinky + 3 Now Kundan + Pinky + Pankaj + Sonu + Pintu = Natural number Convert all into one form, then check with the options, if you wont get the value into fraction form, that number if required answer. Here all is converted into form of Sonu: = 3+ Sonu + Sonu 2 + Sonu + 4 + Sonu + 1 + Sonu + 4 = 6 x Sonu + 10 It is satisfied only when the natural number is 58.

76 C Option A is wrong because

the author does not discuss the origin of the belief. Options B and D are wrong because it cannot be ascertained whether the belief is universally accepted or whether it is well-known.

77 B The movement of capital across the world is discussed in the context of currency valuation and its consequent effect on wages. Since it is unclear as to what effect it has on technology, Statement 1 is incorrect. At present, capital moves freely and makes it difficult to undervalue currencies. This causes increases in the currencys value and hence wages. Thus, if capital movement was restricted, currency valuation and wages could remain low even if productivity increased.

78 C Since wages are influenced by average productivity in the country's economy, low wages despite increased productivity imply that the average productivity has not risen. The role of technology, labour unions or education levels on wage levels in developing countries is not mentioned.
