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?

  1. R is U’s husband.
  2. R is S’s wife.
  3. S is unmarried
  4. None of the above

Answer: B

Explanation

There are two generations. There are 6 members - 3 males (T, S and one other) and 3 females (U, Q and one more). We do not know about the gender of P and R.

There are two couples and rest of the two are unmarried siblings. These are definitely married - P, Q, R. These are definitely single - T. We do not know whether S and U are married or not.

As U is P’s daughter and Q is R’s mother-in-law, it means that P and Q belong to the senior generation and U and R belong to the junior generation.

So, we get the following family diagram:

U and T are the unmarried siblings. R is S’s wife.
