Verbal Reasoning - Blood Relation Test - Discussion

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

Analyze all options and classify all(PQRS etc) as per generation. for generation see introduction (below link)
(+ M, -B, %F, XS)
now first option Q - N + M x P
Q N
M P
Q is brother of N means Q & N are from same generation.
N is the mother of M means M is next generation, and M is sister of P. It means M & P is from same generation.
separate lines for each generation
Q N
M P
now if you analyze above it shows Q is maternal uncle of M&P hence rejected.

now second option P + S x N - Q (+ M, -B, %F, XS)
P
S N Q
here relation is P is mother of SNQ rejected.
fourth option
Q - S % P
P
Q S , conc p is father of Q,S
now third option.
P - M + N x Q (+ M, -B, %F, XS)

N Q
P M , PM are brother sister, their mother is N and her brother is N hence this option is rit.
Further in above question + and % is separate generation.
- and x is separate generation.

@ ariharan.

I would like to suggest something always try to make diagrams relating to blood relation problems. I always look forward to it. Hope you would like it.

1) Take it logically.
2) Let see the options.
3) All we want p on left side(as P is gona be related with Q) and Q on rite side.
4) Also we want * with Q on right side as he is P's mothers brother. Because brother sister relation is shown by * sign.
5) All this pointed toward option C.
6) Make family tree of c.
7) There u got the answer.
