RRB NTPC 2024 CBT 1 Question Paper (28-Aug-2025) (Shift 3)
The correct answer is
Son's wife's father
This question requires determining the relationship between two individuals, B and S, based on a set of familial connections. We can solve this by constructing the family tree step-by-step.
Family Tree Breakdown
- B is the father of O.
- O is the wife of A. This implies A is the husband of O.
- A is the brother of T.
- T is the daughter of S.
Deducing Parent-Child Links
- Since A is the brother of T and T is the daughter of S, it follows that S is the parent of A.
- As O is the wife of A, and S is A's parent, O is the daughter-in-law of S.
- We know B is the father of O.
Final Relationship Determination
We need to find how B is related to S.
- S is the parent of A.
- A is married to O.
- B is the father of O.
- Therefore, B is the father of S's daughter-in-law (O).
- This position (father of daughter-in-law) corresponds to being the father-in-law of the son (A).
- Looking at the options, Option 4, "Son's wife's father", correctly identifies B. If we consider 'Son' as S's son (A), then 'Son's wife' is O, and O's father is B.
