Direction (Q. 1-5) : Read the following information and answer the questions that follow.
P, Q, R, S, T, U, V and W are eight friends. There of them play Hockey and Tennis each two of them play Gold. They all are of different heights. The shortest does not play Hockey and the tallest does not play Gold. U is taller than P and S, but shorter than Q and W. T, who does not play Hockey, is taller than Q and is second tallest. V is shorter than S, but taller than P. W plays Tennis with S, and is fourth from the top. V does not play either Hockey or Gold. Q does not play Gold.
If Y is the sister of L, W is the grand mother of Z.
So, sister (X) of Z will be great-aunt of Z.
If Y is the wife of L, she would be the mother of Z.
So, in this case also Y's aunt X would be the great aunt of Z.
Hence, there are two possibilities:
Y can be either a sister or wife of L.
So, either '-' or '+' can come in place of (?).
