Verbal Reasoning - Blood Relation Test - Discussion

@All.

Maternal uncle is the Correct answer. Please understand the last sentence carefully. How is Bajpai related to the man in the photograph It means the father of my brother. → This refers to Bajpai's father.

"The only daughter of the father of my brother" → This means Bajpai's sister.

"He is the son of the only daughter" → This means the boy in the photograph is Bajpai's sister's son. What is Bajpai's relationship with his sister's son? Maternal uncle.

I think the answer is "none of these", because Bajpai's gender is not given.
Bajpai's related to man--> not known (maternal uncle if Bajpai is male).
Man related to Bajpai. --> nephew (Bajpai's gender is not required for this).

Nephew should be the answer.

@All.

According to me, “The father of my brother” refers to Bajpai’s father.
“The only daughter of the father of my brother” refers to Bajpai’s sister.
Therefore, the man in the photograph is Bajpai’s nephew (son of Bajpai’s sister).

While solving blood relations there are 2/3 basic rules and one of them is you can't decide the gender based on a name unless given to you.

For eg- "aman" can either be a boy or a girl, we don't have to relate the name to the gender.

Therefore Bajpai here cannot be maternal uncle as his gender is not specified.

@All.

The Man related to Bajpai means brother.
Bajpai related to Bajpai means maternal uncle.

I am not understanding the answer. Please explain to me.

I really can't able to understand this, it would be so helpful if someone explain this briefly to me.

How to know Bajpai is male? Here it's not mentioned right?

Bajpai is either male or female.

You are correct, thanks @Jagannath.
