Directions for the following 3 (three) items : · as printed by UPSC
If B scores the least, the rank of C will be
aSecond
bThird
cFourth
dSecond or third
AnswerUPSC’s answer is (d).
B is least, so E cannot be least, which means C cannot be highest (that would make E least). So F is highest, which fits with B being least. D sits directly above A, C is above A, and E is free among the middle places. The possible orders are F C D A E B, F C E D A B and F E C D A B. So C is second or third.
Why each option is right or wrong
(a) Wrong: third is possible, but so is second.
(b) Wrong: second is possible, but so is third.
(c) Wrong: C cannot be fourth, since D and A sit together below it.
(d) Right: C is second or third.
Answer: UPSC’s key. Explanation: written by UPSC Grade, not by UPSC.
