Question

A man is looking at a photograph of a woman and his friend asks him, “Who is she?” The man replies, “I have no brother or sister, but the father of the woman in the photograph is my father’s son.” Who is the woman in the photograph?

• A. His daughter
• B. His wife
• C. His sister
• D. His mother

Hint:

In blood-relation problems, always replace indirect phrases like “my father’s son” using the given family constraints.

Answer 1

The Correct Option is A

To solve the problem, let's analyze the statement made by the man: "I have no brother or sister, but the father of the woman in the photograph is my father’s son."

1. The man says, "I have no brother or sister". This clearly indicates that he is the only child of his parents.
2. He then mentions, "the father of the woman in the photograph is my father’s son." Given that he has no siblings, "my father's son" can only refer to himself.
3. This implies that the woman in the photograph is his daughter, as he is her father.

Let's examine the options provided:

• His daughter: According to our analysis, this is correct because he is referring to his own child.
• His wife: This is not possible as the man referred to the "father of the woman", which signifies a parent-child relationship, not a spousal relationship.
• His sister: He explicitly mentioned he has no siblings, ruling out sister.
• His mother: This is impossible because the photographic subject is referred to as the daughter of the man.

Therefore, the woman in the photograph is his daughter.
