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.

[A]. I alone is sufficient while II alone is not sufficient
[B]. II alone is sufficient while I alone is not sufficient
[C]. Either I or II is sufficient
[D]. Neither I nor II is sufficient
[E]. Both I and II are sufficient

Answer: Option B

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].

I agree with chris.

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 ?

Priya said: (Sep 10, 2013)  
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.

Hitesh Joshi said: (Feb 23, 2014)  
It also doesn't mention that tanya is daughter or son.

Tarun Gaba said: (May 26, 2014)  
Yes he may be his father or maternal uncle.

Akash said: (Jun 20, 2014)  
Here gender of tanya is not given and only on the basis of female name we can't say tanya is female.

Shubham said: (Sep 28, 2014)  
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.

Sathish said: (Mar 17, 2015)  
Agree with @Shubham.

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

Trishul said: (Jul 7, 2015)  
But the gender of Tanya is not given so we can't say whether Tanya is his son or daughter from those two statements. Shouldn't the answer be D then?

Bunty said: (Jul 11, 2015)  
Agree with @Sbhubham.

Chandler said: (Aug 18, 2015)  
Gender of Tanya is not given. How can we conclude that Tanya is man's daughter?

Amit Samota said: (Aug 22, 2015)  
In both the cases the man in the photograph can be Tanya's father or maternal uncle.

So option (D) is correct.

Nitish said: (Sep 7, 2015)  
Clearly it is mentioned in statement 1 that the Tanya's father is the only son of her grandfather. So she is related as daughter.

In case some guys are saying that only son doesn't mean Tanya's grandfather has no daughter, yes it is possible but the old man would be maternal grandfather not the grandfather with respect to Tanya.

Hence the correct option is C. Statement 1 also alone can relate Tanya to the man in the photograph. Yes, gender wise Tanya is a girl off course, apply your common sense people, its a hint.

Sri said: (Sep 18, 2015)  
How can we conclude Tanya's gender is female?

Xyz said: (Oct 10, 2015)  
Here the matter is not about whether Tanya's gender guys. The question is how is Tanya related to the man. So, with the given options we could conclude that the man is the father of Tanya and according to you if Tanya is not a daughter, even then it doesn't matter.

Because that may be a father-son relation or father-daughter relation. But the question is not that. The question is just how is the man related to Tanya.

So the man is the father of Tanya. That's all, stop worrying about Tanya's gender which is just a waste of time and start thinking on drawing the final answer.

Moni said: (Sep 3, 2016)  
I think option (c) is correct.

Xyz said: (Sep 5, 2016)  
The answer should be (C). Because if the man is Uncle then he can't be the "Son" of Tanya's Grandfather.

Yaduvanshi said: (Nov 2, 2016)  
I agree @xyz.

Answer must be (c) either I or II.

Atanu said: (Jan 20, 2017)  
Yes, the answer must be C.

Atanu said: (Jan 20, 2017)  
But I also think that Tanya's grandpa may be from his /her mother's father, so maybe the answer is correct.

Yogesh said: (Apr 1, 2017)  
I think correct answer is C. Both statements say that Tanya's father is tha man in photograph.

Lovish said: (Jun 4, 2017)  
It doesn't matter it Tanya's grandfather has a daughter or not the main concern is the man.

Madhu Sudhan said: (Nov 16, 2017)  
We don't care about gender of Tanya. Tanya is child of the man in the photograph.

Namrata Surve said: (Dec 14, 2017)  
Answer should be c, ultimately both the statements convey the same thing.

Viresh Fattepur said: (Feb 17, 2018)  
Answer should be C since both statements tells samething.

Vincent said: (Feb 26, 2018)  
The answer should have been C. Both statements convey the man as Tanya's father. The gender of Tanya is irrelevant to the answer.

Mike Yako said: (May 15, 2018)  
Definitely C.

If you look at the explanation, both answers end in this phrase, "he is Tanya's father or Tanya is the man's daughter".

Mitesh said: (Feb 28, 2020)  
In case some guys are saying that only son doesn't mean Tanya's grandfather has no daughter, yes it is possible but the old man would be maternal grandfather not the grandfather with respect to Tanya.

As per question option c is correct.

Sai said: (Jul 17, 2020)  
In both cases, the man is Tanya's father.

So, option C is correct.

Sai said: (Sep 1, 2020)  
Right, agree @Jayanathan Ravi.

Manjesh said: (Sep 24, 2020)  
I think C is the correct answer.
