Passage beginning “When three friends A, B and…”

Who wore the sweater ?

aA
bB
cC
dCannot be determined

AnswerUPSC’s answer is (a).

C wears the tie by clue 2, so the sweater is on A or B. Clue 1 says B did not wear the white sweater, and the sweater is the white garment, so B has the jacket and A has the sweater. Check: A is then Kumar, who is ruled out of the jacket by clue 4, which fits. So A wore the sweater.

Why each option is right or wrong
  • (a) Right: A wears the white sweater.
  • (b) B is excluded from the white sweater and wears the jacket.
  • (c) C wears the tie.
  • (d) Clues 1 and 2 together place the sweater on A.
