A + B means 'A is the father of B';
A - B means 'A is the sister of B';
A × B means 'A is the brother of B';

If, R + S × TV is U, then what is the X relation of S with U?

Answer: Option B
Solution (By JKSSB Mock Tests)
Following the expression through standard division/addition logic for the missing symbols, S aligns as a female child one generation below, making her a daughter.
There is a family of five members, K, L, M, N and O. Among them, there is a married couple. L is unmarried and is the brother of K. N is sister of O. M is the only married woman and mother of N. There are only two men in group L and O. Who is the father of K?
Explanation:
Based on the limited valid men constraints (assuming standard interpretation of the typo), L is the male figure completing the couple to M, or otherwise logically serves as the father in standard family tree grids provided in these tests.
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.
