Verbal Reasoning - Blood Relation Test - Discussion

Correct answer is only 1.

Me some what confused, I think there is no need of second statement.

I agree with susmitha, there is no need of second statement.

Ya I am sure only 1 is the correct answer.

@All

You all are wrong. The given answer is correct.

From I: D is MALE, B is MALE or FEMALE. So, we can find only that 'B is SON or DAUGHTER of C'. There is no info to find whether B is male/female in I.

From II: We can find that D is MALE or FEMALE, B is FEMALE.

From I & II: We can find that B is the daughter of C.

Please be careful on solving these kind of questions.

Hope this info may help you a little bit. Have a nice day!

Ya ya I too agree with Mr. Sundar. We must find relation between B and C.

So, the second statement also required to solve this problem.

The given answer is correct. Because we have to know how B is related to C?

And for answering this we need to know that B is male or female.

Because after getting that B is the sister of D we will sure that B is the daughter of C. Without 2nd statement it can be B is the daughter of C as well as son of C.

The son of D is the grandson of C.

So, D may be son in law of C.

In this case, B is not the daughter of C.

Please reply my query.

The answer should be "Data Insufficient", as it is only known that D's son is grandson of C. Here two cases arise: (I) C here could be D's father (hence C becomes paternal grandfather of D's son), or (ii)C could be D's wife's father (hence C becomes maternal grandfather of D's son). In case I B is daughter of C, and in case II B is C's son-in-law's (D's) sister, for which there is no specific term known.

I fail to understand why the concept of paternal and maternal grandfather is not being considered while solving such questions. Also, people, please understand that statement two anyhow will be required (although the question still stays invalid) because unless the gender of B is known, how can one establish B's relationship with anyone?

1 and 2 both are require because we have to relates to B and C(see the question properly). if D is son of C then D's son becomes grand son of C automatically B becomes daughter of C.

So B is the daughter of C.. Answer is D.
