Question 46: Logical Reasoning and Mental Ability
A, B, C and D are students. They are studying in four different cities, viz., P, Q, R and S (not necessarily in that order). They are studying in Science college, Arts college, Commerce college and Engineering college (not necessarily in that order), which are situated in four different States, viz., Gujarat, Rajasthan, Assam and Kerala (not necessarily in that order). Further, it is given that—
- (i)D is studying in Assam
- (ii)Arts college is located in city S which is in Rajasthan
- (iii)A is studying in Commerce college
- (iv)B is studying in city Q
- (v)Science college is located in Kerala
Which one of the following statements is correct?
AnswerUPSC’s answer is (a).
Working: A is at Commerce in Gujarat, B at Science in Kerala and city Q, C at Arts in Rajasthan and city S, and D at Engineering in Assam. City S belongs to the Arts college, so it is C's. D's city is therefore P or R, never S. So statement (a) is correct; the others contradict the working.
Why each option is right or wrong
- (a) Correct: city S is C's, so D is in P or R.
- (b) A is at Commerce, not Science.
- (c) A is in Gujarat; Kerala belongs to Science, which is B's.
- (d) Engineering is in Assam; Gujarat is Commerce's state.
