In a certain code, ‘A + B’ means ‘A is the son of B’; ‘A – B’ means ‘A is the husband of B’; ‘A × B’ means ‘A is the mother of B’; ‘A ÷ B’ means ‘A is the daughter of B’. If P ÷ Q – R ÷ S × T, how is P related to T?
Correct answer C. niece
Explanation
Decoding gives P is the daughter of Q, Q is the husband of R, R is the daughter 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 granddaughter, so P is T's niece.
