In a code, 'A $ B' means 'A is the father of B', 'A * B' means 'A is the sister of B', and 'A = B' means 'A is the wife of B'. If 'P $ Q * R = S', how is P related to S's wife?

Question

Accepted Answer

Father. 'R = S' makes R the wife of S. 'Q * R' makes R the sister of Q, and 'P $ Q' makes P the father of Q, hence also of R. So P is the father of S's wife (R).
