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 mother of B’; ‘A ~ B’ means ‘A is the sister of B’. If P ~ Q < R > S = T, how is P related to T?
Correct answer D. aunt
Explanation
Decoding gives P is the sister of Q, Q is the son of R, R is the father of S, S is the mother of T. Treat each statement as a link in one family tree. Linking them, P is R's daughter, so P is S's sister, so P is T's aunt.
