Question: How many children does M have ?

Statements:

  1. H is the only daughter of X who is wife of M.
  2. K and J are brothers of M.

[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 D

Explanation:

From I, we conclude that H is the only daughter of M. But this does not indicate that M has no son. The information given in II is immaterial.

If H was given to be only child, could we say that answer would still be option D as M may have more than one wives ?

Ankur said: (Aug 15, 2013)  
Option D will be correct cause statement II contradicts I.

Rajkumar Singh said: (Nov 26, 2013)  
In statement 1, h is the only daughter of M, but none of the statement tells about the son of m. Thus both the statement are not sufficient.

Mohit said: (Dec 3, 2013)  
I think in first statement talking about MANY CHILDREN but M have only one child and second statement is immaterial that's why both are insufficient. Answer will be D.

Jaya said: (Jun 24, 2014)  
It is nowhere mentioned in question that M have how many sons? question is how many children so whether it is son or daughter we have to count that, so I think answer should be A.

Bharath said: (Oct 27, 2014)  
X and M are husband and wife so it is saying H is daughter of X so automatically for m also so they have one child. So option is 1.

And it says M has brothers that doesn't need to be cared.

Siva said: (Mar 16, 2015)  
Answer is option(A) because question indicates how many children M have?

So option(A) is sufficient.

Manikanta Gupta said: (Jul 23, 2015)  
The answer is D because no clarity regarding sons of M is given in the data and we are supposed to count the total number of children.

Karthik said: (Sep 1, 2015)  
Why not option A?

Rajesh said: (Jan 20, 2016)  
A could have been answer if I statement was H is daughter of X who is her only child but the statement merely says H is the only daughter of X. Apparently it's inconclusive of number of children X or M have but at same it's conclusive of only number of daughter.

D'Raj said: (Feb 25, 2016)  
If M has only female child that is only H. So what's wrong in this option. If he doesn't have any male child. So option A makes sense. And I think not option D.

Sid said: (Aug 10, 2016)  
Question is only talking about the children not about the gender, don't go deeply with a question feel the essence and go simply for option A.

Chandu said: (Oct 4, 2016)  
Option A is the correct answer.

Why because in question they particularly mention that x has only daughter.

That means there are no other children for x.

Ram Kinkar said: (Oct 24, 2016)  
It should be option A.

Hrishikesh Shelar said: (Nov 9, 2016)  
Option A is the correct answer because,
The question is how many children's M have? IF that daughter is from M to his wife i.e. X. Then & then Only A is the correct answer.

Fiza said: (Feb 22, 2017)  
Option A should be the right answer.

Saro said: (Jul 19, 2017)  
Option A is the right answer.

Saurabh Kumar said: (Jul 26, 2017)  
I think Option A is the right answer.

Ranjith Reddy said: (Aug 25, 2017)  
Statement 1 says that h is the only daughter here the word only means one right so according to me, A is correct.

Shashank said: (Sep 22, 2017)  
It is Option A.

Mani said: (Mar 9, 2018)  
We say (child=only one---boy or girl) but he asked children which is plural (more than one).

Mitu said: (May 20, 2019)  
A is the correct answer.

Bhadru said: (Sep 21, 2019)  
Here, Option A is the correct answer.

Swagata said: (Nov 17, 2019)  
Only daughter means that one child. No?

Otherwise why ONLY is added?

Mitesh said: (Feb 27, 2020)  
We can not assume that M has another child. As given in statement M has only 1 daughter. So answer A is correct.

Damini Dhondge said: (Jan 10, 2021)  
According to me, Only Option A is sufficient.

Vijay said: (Feb 17, 2021)  
Anyone explain the right answer.

Vishnu said: (Mar 17, 2021)  
A should be the answer because we have to count a number of children, not the relationship or it doesn't count or mentioned that m have relationships with anyone else rather than x so (a) is correct because it's clearly mentioned that count child by statement M has only 1 and it says answer (A) is correct.

Sidheshwar Kumbhar said: (Jun 30, 2021)  
Agree, Option A is correct.

Dinesh said: (Aug 14, 2021)  
Option A is the Correct answer.
