In a certain code, ‘A * B’ means ‘A is the sister of B’; ‘A & B’ means ‘A is the daughter of B’; ‘A ! B’ means ‘A is the father of B’; ‘A ? B’ means ‘A is the husband of B’. If P * Q & R ? S, how is P related to S?
Correct answer D. daughter
Explanation
Decoding gives P is the sister of Q, Q is the daughter of R, R is the husband of S. Treat each statement as a link in one family tree. Linking them, P is Q's sister, so P is R's daughter, so P is S's daughter.
