In a certain code, ‘A @ B’ means ‘A is the sister of B’; ‘A # B’ means ‘A is the brother of B’; ‘A $ B’ means ‘A is the husband of B’; ‘A % B’ means ‘A is the son of B’. If P # Q % R % S $ T, how is P related to T?
Correct answer D. grandson
Explanation
Decoding gives P is the brother of Q, Q is the son of R, R is the son of S, S is the husband of T. Treat each statement as a link in one family tree. Linking them, P is R's son, so P is S's grandson, so P is T's grandson.
