Question

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

• A. Aunt
• B. Daughter
• C. Grandmother
• D. Mother
• E. Sister

Answer 1

Answer: (E)

Sister

Let us presume the name of the woman showing the photograph as X and the name of the man in the photograph as Y.
Y's brother's father means Y's father and he is the only son of X's grandfather. This clearly indicates that Y's father and X's father is one.
So, X is Y's sister.
