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