Verbal Reasoning - Blood Relation Test - Discussion

Q is the brother of n, n mother of m, and m is the sister of p.
So m and n are children of n then q will be the maternal uncle of both. So, option A is also right.

P - M: "P is the brother of M".
M + N: "M is the mother of N".
N * Q: "N is the sister of Q".

From this, we deduce:
P is the brother of M.
M is the mother of N.
N is the sister of Q.

What is the relationship between P and Q?
P is the brother of M, and M is the mother of N, so P is the maternal uncle of N.
N is the sister of Q, which means Q is also M's child, making P the maternal uncle of Q.
This expression shows that P is the maternal uncle of Q.

It is easy, you don't need to solve it fully. Let's check...
We have to find that P is an uncle i.e P is male.

a) Q - N + M x P
M x P means
M is the sister of P but is P male or female, we don't know...
So part (a) is rejected.

b) P + S x N - Q
P + S means P is the mother of S.
So P is female..
Again (b) rejected because P must be male.

d) Q - S % P
S % P
This means; S is the father of P but is P male or female.
So part (d) is again rejected.

c) P - M + N x Q
P - M means P is the brother of M.
So P is male, so it is sufficient to prove the answer.

Let's complete it;
P - M + N x Q
P - M means P is the brother of M.
M + N means M is the mother of N.
N x Q means N is the sister of Q.

Conclusion: P is the brother of M, and M is the mother of Q.
So, P is the Uncle of Q.
