Question 55: Logical Reasoning and Mental Ability

Direction for the following 3 (three) items · as printed by UPSC
Passage beginning “When three friends A, B and…”

What is the colour of the tie ?

aBlack
bBlue
cWhite
dCannot be determined

AnswerUPSC’s answer is (b).

From the working so far, A is Kumar in the white sweater, B is Singh with the jacket, and C is Ribeiro with the tie. The colours left for B and C are blue and black. Ribeiro avoids black (clue 5), so Ribeiro's tie is blue and Singh's jacket is black. The tie is therefore blue.

Why each option is right or wrong
  • (a) Black is Singh's jacket, not the tie.
  • (b) Right: Ribeiro, who avoids black, wears the blue tie.
  • (c) White is Kumar's sweater.
  • (d) The clues do fix the tie's colour as blue.

Answer: UPSC’s key. Explanation: written by UPSC Grade, not by UPSC.
