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?

Answer 1

Hint: Read the question very carefully to find the relation between the woman and the man in photograph. The only son of your grandfather will definitely be your father. Use this relation information to solve the question.

Complete step-by-step answer:
We are given that pointing to a man in a photograph, a woman said, “His brother’s father is the only son of my grandfather”.
We have to find the relation between the woman and that man in the photograph.
We can solve this question using Blood relation analysis.
Let the woman be X and the man be Y.
Y’s brother’s father will be the father of Y too.
The only son of X's grandfather will definitely be the father of X (father’s father is grandfather, so son of grandfather is father).
So here the father of the man’s (Y’s) brother is the father of the man too and the son of woman’s grandfather is the father of the woman.
We get that the man’s father is the woman’s father.
Therefore, the man and the woman must be siblings.
Therefore, the woman (X) is the sister of the man (Y). The woman is related as sister to the man in the photograph.
The answer is Sister.

Note: ‘Blood relations’ is one of the trickiest and the easiest, when understood, topics in logical reasoning. Relation is a connection between any two things or two people. Be careful in solving these types of questions because a miscalculation in one relation can destroy the whole answer. If you consider the relation mother instead of considering aunt, then uncle becomes the father. So please be very careful.
