Question: How many sons does X have ?


  1. Q and U are brothers of T.
  2. R is sister of P and U.
  3. R and T are daughters of X.

Only I and II
Only II and III
All I, II and HI
I, II and III together are not sufficient
None of these
Answer: Option

From I, II and III, we conclude that all P, Q, R, T and U are children of X. Of these, Q and U are male while R and T are female. But the sex of P cannot be determined.

Yeah, here it is not written that only these are the children of X. So we can't clarify the statements & hence all are insufficient.

Must be [D].

Even sex of P can be determined. We cannot conclude that X only has 5 kids P, Q, R, T, U. Perhaps, there are A, B, C, D and so on.

Answer should be I and III.

From 1st statement we come to know that Q U T are siblings and Q and U are male.

From III R and T are daughters of X that means Q U T R are children of X and Q U are sons and R and T are females.
