MCQ: Blood Relations - 3(Hard) - SSC CGL MCQ

We can see that if we solve the given relation L @ B @ K – N @ S + T % X, then we will get the family tree as follow:

So, we can see that X is brother-in-law of L.

Hence, option C is correct.

We can see that if we solve the given relation P = Q - R @ S = T - U + V = W, then we will get the family tree as follow:

So, we can see that W is daughter-in-law of S.

Hence, option D is correct.

The decoded equations are as follows:

A # C means A is the father of C

C * E means C is the sibling of E

E # G means E is the father of G

G @ B means G is the grandchild of B

B $ D means B is the mother-in-law of D

D # I means D is the father of I

I * H means I is the sibling of H

Equation: P # Q % R * S @ T % Q

P # Q means P is the father of Q

Q % R means Q is the mother of R

R * S means R is the sibling of S
