Question 78: Logical Reasoning and Mental Ability

Directions for the following 3 (three) items : · as printed by UPSC
Passage beginning “Six students A, B, C, D, E and F…”

If E is ranked third, then which one of the following is correct ?

aE gets more marks than C
bC gets more marks than E
cA is ranked fourth
dD is ranked fifth

AnswerUPSC’s answer is (b).

If E is third, E is not least, so C is not highest. Hence F is highest and B is least. That leaves positions 2, 4 and 5 for C, D and A. D and A must be adjacent with D above A, so they take 4 and 5, and C is second. The order is F, C, E, D, A, B. So C scores more than E.

Why each option is right or wrong
  • (a) Wrong: C is second, above E.
  • (b) Right: C is second and E is third.
  • (c) Wrong: A is fifth.
  • (d) Wrong: D is fourth.
