A family of two generations consisting of six members P, Q, R, S, T and U has three males and three females. There are two married couples and two unmarried siblings. U is P's daughter and Q is R's mother-in-law. T is an unmarried male and S is a male. Which one of the following is correct?
R is U's husband.
R is S's wife.
S is unmarried.
None of the above
Solution
T is an unmarried male and U (P's daughter) is female; T and U are the two unmarried siblings, children of a couple. The parent couple are P and Q. Q is R's mother-in-law, so R married a child of Q. Since T and U are unmarried siblings, R's spouse must be S. S is male, so R is female and R is S's wife.
