A man looks at a photograph and says, ‘I have no brothers or sisters, but this man’s father is my father’s son.’ Who is he looking at?
This is a classic family-relationship riddle. The important clue is that the speaker has no siblings, so there is only one person who can be ‘my father’s son’.
Answer and explanation
The person in the photo is his son. Since he has no brothers or sisters, ‘my father’s son’ means the speaker himself. So ‘this man’s father’ is the speaker.
