Question

A man said, "My mother's husband's only son is the father of your sister's brother." How is the man related to you?

1. A. Uncle
2. B. Father (Correct answer)
3. C. Grandfather
4. D. Brother

Correct Answer

Option B — Father

Detailed Solution & Explanation

The correct answer is Father.

Key Points

• Step through it: 'my mother's husband' = my father; 'my father's only son' = the man himself; 'your sister's brother' = you.
• So the man is the father of you — your father.
• Replace each clause with the single person it denotes, one layer at a time; the self-references ('only son', 'sister's brother') collapse the puzzle to a direct link.
