If Y is selected and B is rejected, the team will consist of which one of the following groups ?
aA, C, W and Y
bA, C, X and Y
cA, C, Y and Z
dA, W, Y and Z
AnswerUPSC’s answer is (b).
The rules: at least two males, and the pairs B-W, C-Z and W-Y cannot play together. With B rejected, the only males available are A and C, and two males are needed, so both are in. Y is selected. Z cannot play with C, so Z is out. W cannot play with Y, so W is out. The fourth member must therefore be X. The team is A, C, X and Y.
Why each option is right or wrong
(a) Wrong. W cannot play with Y, who is in the team.
(b) Right. A, C, Y and X break none of the pair restrictions and include two males.
(c) Wrong. Z cannot play with C.
(d) Wrong. W and Y cannot play together, and the team has only one male.
