Show Answer

Correct Answer :

Option A

Solution :

The correct option is Z.

Step-by-Step Explanation:

Let's analyze the given statements step by step to determine the relationships in the family:

1. Identify A and Q:
"A is the only son of Q who is the brother-in-law of Y."
This means Q is male (+) and has a son A (+). Q is married to someone who is a sibling of Y, or Y is married to Q's sibling. Since Y is unmarried ("Y is the unmarried brother of Z"), Y is a male (+) sibling of Q's spouse. Thus, Q is married to Z or another sibling, making Q the brother-in-law of Y.

2. Analyze Z and Y:
"Y is the unmarried brother of Z."
Since Y is a male (+) sibling of Z, Z is Q's spouse. Since Q is male, Z must be female (-). Together, Q (male) and Z (female) are married. Therefore, Z is the mother of A.

3. Analyze A, V, B, U, and X:
- "V is the daughter-in-law of A." This means A (+) is married to someone, or A's son is married to V (-).
- "U is the mother of B but she is not the spouse of Q." Since U (-) is a mother, she is married. A is married to U (-), making B their child.
- Since V (-) is the daughter-in-law of A, V is married to B (+).
- "X is the paternal aunt of B." A paternal aunt is the father's sister. Since A is B's father, X (-) is the sister of A (+).

4. Check Family Rules & Constraints:
- "No single parent has a child": All parents (Q & Z, A & U) are married couples.
- Family members:
Males (+): Q, Y, A, B (4 males)
Females (-): Z, X, U, V (4 females)
- "Equal number of males and females are there in the family": 4 males and 4 females (Total 8 members).

Conclusion:
Z is the spouse of Q and the mother of A. Therefore, Z is the mother of A.
