Question

Pointing to a photograph, a man said, 'She is the daughter of my grandfather's only son.' How is the woman in the photograph related to the man?

• A. Mother
• B. Sister
• C. Aunt
• D. Cousin

Hint:

First work out exactly who 'my grandfather's only son' must be relative to the man, then ask what a daughter of that person is called.

Answer 1

The Correct Option is B

The grandfather's only son is the man's own father. The daughter of the man's father is the man's sister. She is not his mother (his mother is his father's wife, not the father's daughter), not his aunt (an aunt would be his father's sister, i.e. the grandfather's daughter), and not a cousin. The correct option is 'Sister'.
