Question

In a family of nine members, how is N related to J?

Consider the following statements:

I. P is the spouse of J who has only two children. K is the grandchild of P. V is the sister-in-law of B.

II. B is the only son of J. L has no siblings. K is the nephew of R and brother-in-law of V.

III. L is the sister-in-law of R. R is the only sibling of B. C is the brother-in-law of B. N is the niece of R.

Based on the above, choose the correct option regarding the sufficiency of the statements to answer the question.

Accepted Answer

**Solution:**

1. From Statement I:
   - P is the spouse of J, and J has two children.
   - K is the grandchild of P.
   - V is the sister-in-law of B.
   However, this information alone does not clarify N's relation to J.

2. From Statement II:
   - B is the only son of J.
   - L has no siblings.
   - K is nephew of R and brother-in-law of V.
   This gives some family structure but still does not clearly define N's relation to J.

3. From Statement III:
   - L is sister-in-law of R.
   - R is the only sibling of B.
   - C is brother-in-law of B.
   - N is niece of R.
   Combining this with Statement II, since B is J's only son and R is B's only sibling, N being niece of R implies N is related to J through R and B.

Therefore, Statements II and III together provide sufficient information to determine how N is related to J, while Statement I is not necessary.

**Answer:** (c) If the data in statements II and III are sufficient to answer the question, while statement I is not required.
