If A is the brother of B; B is the sister of C; and C is the father of D, how D is related to A?

[A]. Brother
[B]. Sister
[C]. Nephew
[D]. Cannot be determined

Answer: Option D

Explanation:

If D is Male, the answer is Nephew.

If D is Female, the answer is Niece.

As the sex of D is not known, hence, the relation between D and A cannot be determined.

Note: Niece - A daughter of one's brother or sister, or of one's brother-in-law or sister-in-law. Nephew - A son of one's brother or sister, or of one's brother-in-law or sister-in-law.

A-brother -B;
B-sister - C;
C- father -D,

here A,B,C are brothers and sisters
D is related to A?

So D is Father to A.

Hey vinay,

Given C is father of D

As A(M),B(F),C(M) are brothers and sisters....

D is Uncle of A....

But we don't know whether A is male or female....

So answer cannot be determined...

Renuka said: (Oct 11, 2011)  
Yes you are right. Pradeep koney, but the explanation is different see once.

Anand said: (Dec 22, 2011)  
The answer will be "c" because whatever you give the explanation is right, but niece is not there in the option. So we conclude that the answer is definitely "C".

Anshu said: (Mar 31, 2012)  
@ anand.

Since the option given is nephew the answer could be niece too. Therefore the option of can't be determined that's "D" is the correct option. I hope you understand.

I want to do and know thats problams. How I solve that.

Ouamma said: (Apr 2, 2013)  
Whatever the options be when the sex is not mentioned the answer cannot be determined.

Neeleshsin said: (Jul 1, 2013)  
Hey but here is mention A is brother of B, B is sister Of C, that means A is male candidate.

Suchithra.M said: (Aug 3, 2013)  
I can't understand it. Can anyone explain more this question?

Here given that A, B, C are brother's and sister's.

A - Male.
B - Female.
C - Male.
C Is the father of D.
D - Should be the cousin of A.

My question is how D is the niece or nephew of A?

Aditya Kulkarni said: (Sep 1, 2013)  
Hey @Vinay,

If the Option given is nephew which is the near most relation to A & hence Whatever the options be when the sex is not mentioned we will not consider it & hence I think option c "nephew" is correct answer.

As far as my Knowledge if wrong please discuss further.

B Rajesh Kannan said: (Nov 22, 2013)  
I differ with the explanation given.

C is the father of D, B is the Sister of C i.e D's aunt.
A is brother of B i.e C's brother i.e D's uncle.

If anybody do not agree with me, kindly reply.

Jass Singh said: (Dec 21, 2013)  
A is brother of B.
B is sister of C.
C is father of D.
D is relation of A?

ANSWER: D IS FATHER OF ALL.

Santhost said: (Aug 12, 2014)  
@Suchitra.M

See (Given), A is brother of B.
B is sister of C.
C is father of D.

so, A (male), B (Female), C (Male) are brothers & sisters

Here A is brother of C;

that is A's brother's (i.e.C's), son D will be Nephew/Niece based upon D's sex;

ANSWER: OPTION D

Abhijit said: (Mar 12, 2015)  
As per question.

A (Male).
B (Female).
C (Male).

C is defined to be the father of D. So the only option is D.

Manish Kumar Tripathi said: (Jun 7, 2015)  
Define nephew: A son of your brother or sister usage, synonyms, more.

I think the correct answer is "C" because NEPHEW is given in the 4 option. No matter in male or female. In this question only say relation with D AND A.

Shahbaz said: (Jul 12, 2015)  
[]=male.
() =female.

Now start:

a brother of b.
b sister of c.

Since c is father of d it means c is male.

Here d^s gender is not defined then we have to chose answer 4.

Shubh said: (Aug 10, 2015)  
Exactly A is uncle of D.

Faizan said: (Oct 19, 2015)  
A = Brother (m) of B.

B = Sister (f) of C.

C = Father (m) of D.

D = ? m or f.

Therefore answer is D.

Note: A+B+C are brother and sister.

If D is male answer is NEPHEW. If D female answer is NIECE.

Harish said: (Nov 12, 2015)  
A is the uncle of D.

Ark said: (Mar 2, 2016)  
Niece--> a daughter of your brother or sister and a daughter of your husband's or wife's brother or sister.

Their son is called your nephew.

Surendra Singh said: (Mar 13, 2016)  
Whether, D is male or female not given so according to relation it could be NEPHEW or NIECE but clearly mentioned in options "[D]. Cannot be determined" so we have to select that one only.

Arfa said: (May 11, 2016)  
Good explanation. Thankyou!

Syed Hamd Hafeez said: (Jul 15, 2016)  
Good @Faizan.

Nice Explanation.

Mamatha said: (Jul 30, 2016)  
Here the question is how D is related to A.

According to A, brother's son (or) daughter will be a nephew (or) niece.

If they ask how A is related to D then,

According to D, father's brother (or) sister will be an uncle (or) aunt.

So,the answer is D because they didn't mention the gender of D in question.

Ranjitha S N said: (Jul 31, 2016)  
Nephew is more appropriate than the option can't be determined, right?

Because the answer is either nephew or niece. Instead of roughly saying can't b determined. We can select one of the possible answers that is nephew right?

Nasir Hasas said: (Sep 18, 2016)  
A, C = Male,
B = Female,
C = Father of D.

It means that A, B, C are brother & sister with one another and D is their cousin. Hence A will be the uncle of D.

Aman said: (Oct 20, 2016)  
Hi, everyone option D is the right answer. Because D is son or daughter of C then it is a nephew or nice of A.

Lakhveer Singh said: (Nov 8, 2016)  
I think A and D are brothers.

Vinod said: (Feb 7, 2017)  
@Lakhveer Singh.
Here A, B &C are siblings.
And in problem, clearly given that C is the father of D. &D is either male or female which is not confirm.
So we can not determine its gender.
Therefore option[D] is the right answer.

Yenshi said: (Feb 25, 2017)  
A+..........B-............C+ (brother and sister) ......D+/- (son or daughter).

So, it sex of D can't be determined.

Abhishek said: (Mar 11, 2017)  
(C) is partially correct not fully because you do not know D is MALE or FEMALE(it may be nephew or niece).

So you should go for option (D).

Razak Khan said: (Jul 13, 2017)  
The right answer is d (can't be determined) because we don't know A is male or female.

Bhawana Dubey said: (Aug 25, 2017)  
But I'm confused here because /A -brother B-sis;C-father then D relation of A is the brother.

Yolosqud said: (Aug 31, 2017)  
We cannot say answer because we don't know the gendetr of D.

Shubh said: (Nov 29, 2017)  
D's gender is not mentioned. So how we can consider that D is male or female. So the answer is CND.

Prasanna said: (Dec 28, 2017)  
Can anyone solve this question?

If A is the father of C, D is the son of B, E is the brother of A and C is the sister of D how B is related to E?

Abhishek said: (Feb 6, 2018)  
@Prasanna

A is father of c ---->A(father) for C.
C is sister of d ---->C(sister) for D(male person).
A's brother is E.

D is son of B means A (male)and B(female) married couple and their children C and D
so that B female and E male so that should be sister-in-law.

Alan said: (Apr 30, 2018)  
When it's asked how D is related to A des it means what D is of A?

Please clear my doubt.

Kalpesh said: (Jul 19, 2018)  
I thought it should be Nephew.

Ahmed Hussain said: (Nov 6, 2018)  
A is the brother of B and B is the sister of C and C is the father of D.

So, A+B-C are brother and sister. D is either son or daughter of C. Hence D is related to A is an uncle.

Nishikant Kumar Srivastav said: (Nov 16, 2018)  
I don't think that answer will C.

Because it is not described that C is the father of D.

Mylarappa said: (May 12, 2019)  
Yes, you are correct, Thanks @Rajesh Kannan.

Aqib said: (Jun 20, 2019)  
It will be D.

Because A and C are brothers B their Sister and C is the father of D.

So, obviously, if it is male it will be nephew if female it will be niece.
