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?

Correct Answer: R is S’s wife.

Step-by-step Explanation:

1. Analyze the given information:

• Total members = 6 (P, Q, R, S, T, U)

• Gender distribution = 3 males and 3 females

• Generations = 2 generations

• Relationships = 2 married couples and 2 unmarried siblings

2. Deduce individual details and relationships:

• T is an unmarried male (Gender: Male).

• S is a male (Gender: Male).

• U is P’s daughter (Gender: Female, Generation: 2nd generation relative to P).

• Q is R’s mother-in-law (Gender: Female, Generation: 1st generation).

3. Determine the family structure:

Since there are 2 married couples across 2 generations:

• Generation 1 must contain one married couple (P and Q).

• Since Q is a mother-in-law, Q is married to P (P is male, Q is female).

• Generation 2 contains the children: U (daughter), T (unmarried son), and another married son who is married to R.

• The remaining male is S, who must be the married son in Generation 2. Therefore, S is married to R.

• Since S is male, R must be female (making R the wife of S).

• The two unmarried siblings are T and U.

4. Summary of members and genders:

• Males (3): P, S, T

• Females (3): Q, R, U

• Married couples: (P, Q) and (S, R)

• Unmarried siblings: T and U

5. Verify the options:

• Option 1: "R is U’s husband." – Incorrect (R is female, and R is married to S).

• Option 2: "R is S’s wife." – Correct.

• Option 3: "S is unmarried." – Incorrect (S is married to R).

Hence, the correct statement is R is S’s wife.
