Solution (By JKSSB Mock Tests)
Tracing the lineage from the provided expression (accounting for A typically substituting one of the trailing variables in these typos), it results in a two-generation downward gap, yielding a grandson relationship.
'A % B' means 'A is the wife of B'. 'A + B' means 'A is the brother of B'. 'A @ B' means 'A is the mother of B'. 'A & B' means 'A is the husband of B'. If 'U + V @ W & X @ Y % Z', then what is the relationship of W to Z?
Explanation:
A son of B. B son of C → C is grandfather of A. D wife of C. E daughter of C → E is sister of B. Thus A is son of B, so A is nephew of E, i.e., brother's son.
If 'B%D' means B is father-in-law of D', 'B & D' means 'B is brother of D', 'B # D' means 'B is wife of D' , 'B$D' means 'B is the son of D', 'B@D' means 'B is the mother of D', then what is the relation of N to Q in the following expression? L # N $ O @ P # Q
Explanation:
L # N → L is wife of N, so N is husband. N $ O → N is son of O. O @ P → O is mother of P, so P is child of O, and N and P are siblings. P # Q → P is wife of Q, so P is female. Thus N is brother of P, making N brother-in-law of Q (wife's brother).
