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. Sister
• B. Mother
• C. Aunt
• D. Daughter

Hint:

Grandfather's only son is the man's father.

Answer 1

The Correct Option is A

Work backwards from the woman. $Woman = daughter\ of\ (father)$. The father's daughter, from the man's viewpoint, shares the same parents as the man, so she is his sister.
