Verbal Reasoning - Blood Relation Test - Discussion

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

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.

Nice explanation mytyli sister. Thanks.

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

Ya anu's explanation is quiet easy.

Good explanation anu.

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.

Is any shortcut for these type of Questions??

Thank u Mythili & Ravi.. Both explanations are very nice.. and make easy to understand..
