ANSWERS AND EXPLANATIONS

SECTION V:  LOGICAL REASONING

161. (c)  Mother-in-law of the son of the man’s wife will be the mother of the man’s son’s wife and so the man will be the lady’s father-in-law.

162. (a)  The net effect of a 135 degree turn anticlockwise and a 90 degree turn clockwise will be a 45 degree turn anticlockwise and so the final direction will be East.

163. (d)  The differences are 2, 6, 10 and so on. Therefore, the next difference must be

14 and so the required term = 19+14 = 33.

General explanation for questions  164–166

          x            x           x Verbal x            

1. Also, there must be a gap of 2 days between the GD and interview assessment.

Therefore, neither GD nor the interview assessment can be on Monday.

So, one out of GD or interview assessment will be on Tuesday and the other one will be on Friday.

2. Reasoning cannot be scheduled on Monday and so reasoning will get scheduled on Wednesday and quant will get scheduled on Monday.

Quant x GD/Interview x Reasoning x Verbal x GD/Interview.

164. (a)

165. (c)

166. (b)

General explanation for questions  167–169

We first compare MORE, REST and their codes. R and E will be 6 and 9 in no particular order. Comparing with TIME, E will be 6 and R will be 9.

Comparing MORE and TIME, M will be 7 and so O will be 8. T will be 2 and S will be 5.

I will be 1.

167. (d)

168. (a)

169. (b)

170. (c)

171. (a)  Required value = √182+242

= √324+576 = √900 = 30.

172. (c)  The series is (multiplied by 2) +1, (multiplied by 2) –1 and so on.

Therefore, 43 x 2–1 = 86–1 = 85.

173. (d)  20C2 + 15C2 = 295.

174. (c)  The basis of coding is one from the back and one from the front alternately with an increment of one.

175. (d)  n = 6 cm / 1.5 cm = 4

Number of small cubes = 4 x 4 x 4 = 64.

176. (d)  Neither  is  implicit.  The  Ad  mentions  a  David  Guetta  live  in  Delhi.  From nowhere can it be assumed that he is a writer. II again cannot be assumed.

177. (a)  Only I can be assumed. If criminals knew that cops were about, they would be less inclined to commit such crimes; also policing would ensure that nobody could stop on such roads for extended periods of time without a cop stopping over. II cannot be assumed to be the only reason behind rapes and other such violent crimes.

178. (c)  Both I and II are implicit. Since a consensus has emerged, so it means that both I and II are implicit.

179. (d)  Neither can be assumed from the given statement.

180. (a)  Only I can be assumed from the given statement as if the Supreme Court

wanted Srinivasan to be involved in BCCI matters, he would not have to give the undertaking that he has given. II cannot be assumed.

181. (b)  In selling toys, there is no real need for salesmen but when selling clothes, generally people expect to get personal services and this is what the Tiny Tots store assumes not to be true. So they take the idea that no personal selling is required for clothes and base the new concept on it.

182. (b)  Here the idea is to take each and work backwards from there. Frame each option into a question and see if the argument would be helpful in answering that question and this is how you can arrive at an answer.

183. (c)  Look for the one that is not a benefit. So (c) is the only one which says that there will be a problem with the cloned varieties due to genetic similarities.

184. (d)  Here we are looking at the first step of the buying process and that needs identification. Once a person has determined if they need a personal computer, then and only then will they worry about the user friendliness or other features of the PC. So       (d)      has to be the correct answer.

185. (d)  As assumption is one which if not true would make the argument incorrect. If (d) is negated then the argument would become false and so it is the correct answer.

186. (b)  Only II is a strong argument. (a)  mentions increasing the popularity but the question is not looking at increasing the popularity of the Gita. (b) is a strong argument because it gives us a reason why making Gita India’s principal granth would not be a good idea.

187. (d)  Neither is strong. I is weak as it is ambiguous. II is irrelevant, so it is weak.

188. (d)  Neither is strong. I is not strong as it does not answer the question whether such organisation should be banned or not. II is not strong as it asks a question and does not give a reason.

189. (a)  I is a strong argument as it gives a strong reason of safety and service for banning these taxi services. II is an irrelevant argument as it has no impact on the issue at hand.

190. (b)  I is weak as it is factually incorrect. II answers the question being asked and so it is a strong argument.

191. (c)  A is true but R is false. Refer Google.

192. (a)  Both A and R are true and R is the correct explanation of A. Refer Google.

193. (a)  Both A and R are true and R is the correct explanation of A. Refer Google.

194. (b)  Both A and R are true but R is not the correct explanation of A. Refer

Wikipedia.

195. (b)  Both A and R are true but R is not the correct explanation of A. Refer

Wikipedia.

196. (c)  If both the statements I and II are effects of independent causes. Both States must be doing these for their own purposes so they have to be effects of independent causes.

197. (d)  If both the statements I and II are effects of some common cause. It is possible that a festival has been going on in an area of the city and that is why  there  are  jams  in  that  area  and  also  why  so  many celebrities  are frequenting the city. The connect between the two is the two week period otherwise these could have been effects of independent causes also.

198. (b)  If statement II is the cause and statement I is its effect. Putin arrived in India and that is why Modi tweeted a welcome message in Russian. So II is cause and I is effect.

199. (a)  If statement I is the cause and statement II is its effect.

200. (b)  If statement II is the cause and statement I is its effect. Ask why with I and you will get II as the answer.

ANALYSE YOUR PERFORMANCE

Logical reasoning

A normal section with some bouncers which are not common. However, anyone who has given more than 2 mocks would recognise most of these questions. As is the case normally, the questions were from past years’ papers with some twists to keep the mind running. Completely new questions were also present which cause the test-taker to think before an answer. All in all an interesting section which was a mixture of old and new at the same time; thus, it prepared the student for the fact that questions are repeated and also not to panic in case of any deviation from the said repetition.

Logical reasoning

1.  Analytical:  The analytical section  was  not  too  tough,  though  some blazers existed which forced the student to think about the questions and apply the basic concepts. The question type should not have been alien for a student who had gone through the material, but some of the questions were tricky. A score of 11+ would be good and below 8 would need hard work.

2. Assumption questions: A couple of questions which have obvious answers, most of the section cannot be judged objectively due to the variety of correct answers. At least 2 out of the 5 questions had fairly obvious answers while the others needed a bit of thinking. The section would have taken time and should have been left for the end.

3. Passage-based: An easy section, each question would require one reading of the passage to get the answer, the scores should range between 4 and 5.

4. Strong–Weak: Can’t say, questions seem tricky and need concentrated reading a couple of times to understand what the question requires and following that answering should become easy; however, answers may vary even after that.

5.  Assertion–Reasoning: GK based questions with maths as well, the section requires fair knowledge of science and literature, anything above 1–2 would be good.

6. Cause–Effect: Simple section, no blazers which make the section tough, it is easy to understand where connections exist and where none are possible, 3 would be average while a 5 would not be unachievable.
