Answer: Option A
Solution (By JKSSB Mock Tests)
D is A's husband. G is A's sibling, and E is G's son. Therefore, E is D's nephew.
'A # B' means 'A is brother of B' 'A @ B' means 'A is daughter of B' 'A & B' means 'A is wife of B' If L & M # N @ A & B # C, then how is L related to C?
Explanation:
L & M → L wife of M. M # N → M brother of N. N @ A → N daughter of A. A & B → A wife of B. So A and B are parents of N. M being brother of N is their son. Thus L is daughter-in-law of A and B. B # C → B brother of C, so C is sibling of B. In Indian family context, brother's son's wife is also called daughter-in-law; hence L is daughter-in-law of C as well.
A % B means, ‘A is the son of B’. A # B means, 'A is the daughter of B'. A & B means, 'A is brother of B'. A @ B means, 'A is sister of B'. In W @ Q % R & S & T, what is the relation of W to T?
Explanation:
W @ Q → W sister of Q. Q % R → Q son of R. So R is parent of Q and W. R & S → R brother of S. S & T → S brother of T. So R, S, T are brothers. W is daughter of R, thus W is niece of T, i.e., brother's daughter.
