Question: How is Tanya related to the man in the photograph ?

Statements:

  1. Man in the photograph is the only son of Tanya's grandfather.
  2. The man in the photograph has no brothers or sisters and his father is Tanya's grandfather.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
Both I and II are sufficient
Answer: Option
Explanation:

From I, we conclude that the man is the only son of Tanya's grandfather i.e. he is Tanya's father or Tanya is the man's daughter.

From II, we conclude that the man's father is Tanya's grandfather. Since the man has no brothers or sisters, so he is Tanya's father or Tanya is the man's daughter.

Statement I: Man in the photograph is the only son of Tanya's grandfather.

The man in the photo is the only son of the grandfather. but the grand father could of had a daughter(s).

The man in the photograph could be either tanya's father or uncle.

Therefore the answer should be [B].

From I, it can be so that the man in the photography can be Tanya's Uncle (if the grandfather is from maternal side). Hence it cannot be said for sure it is her Father or Uncle.

From II, it is evident that the man does not have brothers or sisters. Hence if he is the ONLY child of Tanya's grandfather, he has to be Tanya's father.

Therefore, answer is B.

But it is said man is only son of tanya's grand father meaning he is the father of tanya how can he be uncle or any ?

Only son doesn't imply that grandfather doesn't have a daughter. Tanya has two grandfathers (one from mothers side and one from her fathers side). You can think now.

It also doesn't mention that tanya is daughter or son.

Yes he may be his father or maternal uncle.

Akash said:   1 decade ago
Here gender of tanya is not given and only on the basis of female name we can't say tanya is female.

Shubham said:   1 decade ago
From statement 1 the man can be Tanya's father or uncle but from statement 2 he is only father of Tanya. SO ACCORDING TO ME ANSWER CAN BE OPTION C EITHER ONE OR TWO IS SUFFICIENT.

Agree with @Shubham.

He is anyways a related person to Tanya irrespective of uncle or father. He is in her family.
