Everyone here is just explaining the given answer but how did you got that ans? can any one tell me?

Good explanation anu.

Ya anu's explanation is quiet easy.

I like anu's explaination. Its quite easy to understand from backwards.

Nice explanation mytyli sister. Thanks.

Lets move from back. N and Q are sisters. Now both N and Q are daughters of M. Clear!. P is brother of M. i.e., if you are the child then your mothers brother is the paternal uncle.

It's most interesting question in alover the set. I liked it very much and it is a wonderful website.

* Maternal uncle means mother's brother
* Here P must b a mother's brother of Q i.e P is a maternal uncle of Q.its given in question
* P-M+N*Q - means brother, + means mother, * means sister
* Now its clear P is the brother of M & q is the child of m,so p relates to q is maternal uncle

p (brother)-> M (mother) -> n & q

hope u all understand :-)

I didn't understand it please explain me?
