Direction for the following 3 (three) items · as printed by UPSC
What is C's surname ?
aRibeiro
bKumar
cSingh
dCannot be determined
AnswerUPSC’s answer is (a).
Clue 2 gives the tie to C, leaving jacket and sweater for A and B. Read clue 1 as saying the sweater is white and that B and Ribeiro are different people. B does not wear the white sweater, so A does. A is not Ribeiro (clue 1) and not Singh (clue 3 bars Singh from white), so A is Kumar, which agrees with clue 4. B is not Ribeiro, so B is Singh and C is Ribeiro.
Why each option is right or wrong
(a) Right: A is Kumar and B is Singh, leaving C as Ribeiro.
(b) Kumar wears the white sweater, which is A's, so C is not Kumar.
(c) Singh must be B, who wears the jacket; C is not Singh.
(d) The clues do fix the arrangement once clue 1 is read as above.
