Passage: There are eight members in a family: J, M, Q, R, S, T, X and Y. There are three married couples in the family. No child has a single parent. Q is the brother-in-law of S. J is the only sister of S's spouse's father. Y is the grandchild of X. M and T have the same gender. Q is the husband of Y's aunt. M does not have any sibling. Q has only one niece. R is the father-in-law of X's daughter-in-law. Question: Which of the following statements is correct?

1. S is the father of T. M is the wife of S.
2. S is the son of X.
3. Y is the daughter of T.
4. Y is the daughter of T.

Correct answer: Y is the daughter of T.

Solution

The clues about three married couples, Q being the husband of Y's aunt, and Y being X's grandchild allow a unique family structure. In that structure, T is one of Y's parents and Y is identified as T's daughter. Hence the correct statement is that Y is the daughter of T.
