Verbal Reasoning - Blood Relation Test - Discussion

@All

The given answer is correct. Don't get confused. Let me explain.

Assume that, your grandfather has only one son.

This means that your grandfather CANNOT be the Father of your Mother. Because he has only one son. So he (your grandfather) is Father of your Father.

Now son of your grandfather's son (i.e. son of your father) is definitely your brother.

In the given question, Lata can be a Male or Female, but answer is BROTHER.

I hope this will help you. Have a nice day!

Does only son mean that he (the father or mother) has ONLY one son or that he has only ONE son. You see the problem here?

The former means that the grandfather had to be the father of Lata for which the answer given is right. Brother.

But the latter could mean that the grandfather had one son and x no.of daughters, one being Lata's mother. And the son of Lata's Mother's Brother would be her cousin. And hence the question is either incorrect or the answer is option D.

"He is the son of the ONLY SON of my grandfather" does not means that that grandfather is not having any daughters, it means that there is only one son but did not mention information about daughters of grandfather so there may be a chance of having daughters also to the Grand Father.

If Lata is the children of grand father's daughter then the relation will become "option C: Cousin".

So, I suppose the answer is option D.

The answer for the question may be (A) (C) (D). Because the question only mentions that the grandfather only had one son but not only one child. From this we may come to a conclusion that Lata may also be the daughter of the mother and the man in the photograph may be her cousin. So here we can say that the data provided is not sufficient enough to come to a conclusion.

Question is easy one but requires some kind of Logic.

He is the son of the only son of my grandfather.

My grandfather = Latta's Father's Father (Agreed).

Only son of Latta Grandfather = Father of Latta or only son of grandfather.

Son of father = child/Boy/Man and latta is her sister.

1) Grand Father-> 1) (i)Father-> ii) Boy/Man/Child and latta.

The correct answer would be DATA INADEQUATE since two cases is possible. One, where Lata's Mother is the sister of THE ONLY SON (of grandfather), which means the son of the only son is a cousin of LATA.

Secondly, Lata's father is the ONLY SON, which makes the son of the only son, Lata's own brother.

Anyone, please gie me the correct answer.

I thought we were not supposed to assign gender based on the name. In some questions, the name Kiran is used for both boys and girls.

Since it is not mentioned in the question about Lata's gender, it is not correct to decide on the answer to the question as Brother.
So, According to the things I've learned, it's data inadequate.

The question mentioned that his grandfather has only one child is that his father, the second part said that the boy in the photograph is his father's son. So it's clear that his father has two child lata himself/herself and the boy who is in the photograph. So the boy is a brother to Lata both are siblings.

The question mentioned here is Lata's grandfather. The grandfather can be Lata's Maternal Grandfather or Paternal Grandfather. If the grandfather is paternal grandfather, then the man in the photo is a brother to Lata. If the grandfather is a maternal grandfather, then the boy is a cousin to Lata.

Here they have mentioned the only son but that doesn't mean Lata's grandfather cannot be having a daughter and one son.

Here there are two possibilities one is;

She may be the daughter of that only son of her grandfather or Her grandfather could have had one son and another daughter.
