Verbal Reasoning - Blood Relation Test - Discussion

The second statement cannot support the question.

So, sentence one is alone sufficient.
only 1 is correct.

@All.

Both statements are required for us. Without a second statement. We can't know the gender of B. Without knowing the gender. How can we related to C?

The given answer is correct.

Because we find the relation between B and C.

So the relation between B and C is brother and sister.

Therefore both statement is required.

I think only statement 1 is required as the relation of B is asked wrt C. So B is the father of C can b explained with statement 1 itself. If the question was how C is related to B then 2nd statement was required. Hence the answer is A.

The given answer is correct.

Because we find the relation between B and C.

So, the relation between B and C is brother and sister.

Therefore both statement is required.

No, I think it should be only 2. We need to find the relation between B and C. From 2, we come to know that B is a girl. It is sufficient to say B will be a daughter of C, irrespective of the gender of C.

Both 2 statements are required. Because according to the question D is the brother of B . It means we don't know B is male/female.

So according to the first statement ' The son of D is the grandson of C .So here we can know C is the father of D . And second statement say ' B is the sister of D . So about two statements we can know,

C is the father of D.
B is the sister of D.
B is the daughter and D is the son of C.
So finally B is female.
Hope you guys understand.

The answer is only 1 because C is the parent of B.

How D is correct? Please explain to me.
