In a family, P is the mother of Q, Q is the brother of R, and R is the wife of S. How is P related to S?

P is S's mother-in-law. P is the mother of Q, and Q's sister R is also P's child. Since R is married to S, P is the mother of S's wife, which makes her S's mother-in-law.

Explanation

P is the mother of Q, and Q is the brother of R, so P is also R's mother. R is the wife of S, so R's mother P is S's mother-in-law. 'Mother' is wrong because P is the mother of S's wife, not of S.
