Verbal Reasoning - Blood Relation Test - Discussion

Thanks all for explaining the answer.

Ans D is correct.
M is F of N ;
N is Sis of B;
So, C is the brother of B.

Option A is also the right answer.

I think it's Option A.

Please explain this one.

M has one daughter (N) and one son is (C) and C is the brother of F (gender not clear).
As M has three child,
In this condition 4 option is correct.

A is bro of B (if +),
A is sis of B ( if -) ,
A is the father of B (if x).

The question says what equation says the C is the son of M.

By Cross-checking, we got a hint. (A × B - a is the father of B)

Our question is to check whether C is the son of M.
Or (M is the father of C)

So, Option D is correct.

Thank you @Vikas Saini.

The text may look as lengthy but it will be very helpful to solve the relation related questions and save your time also.

The trick to solve the question is as follows:
Step 1: make out the conditions from the question, for example in this question it says ''c is the son of M''. here we can configure the conditions as follows-
Condition 1- c must be a male in the equation.
COndition 2- M should be father or mother in the equation.

Based on these conditions we can filter the options and the remaining conditions can be checked finaaly to confirm the answer. for example in this question :

1st option: c+f means c is brother of F. it confirms that c is a male. and M-N means M is sister of N, here M is neither a father nor mother, so this condition we can take it as a wrong and can avoid it.

2nd Option: C+N means C is brother of N, it confirms that C is a Male. N*M, here M has came in last, so we can not determine the sex of M. So this Option also we can filter out.

3rd Option: F*C means C came in last of the equation and we can not determine the sex of the C. this also we can filter it out.

the remaining option is four. so we can check the fourth option to check it is correct.

Basically on the basis of the question we have to make the conditions and on the basis of these condition we have to filter out the options.

Do practice of it, and you will find very easy to solve these types of questions.

Why not Option A? Please explain.
