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

'P @ Q' means 'P is the sister of Q' 'P & Q' means 'P is the mother of Q' 'P # Q' means 'P is the husband of Q' If 'A # B & C @ D # E' then how is E related to B?
Explanation:
A # B → A husband of B. B & C → B mother of C. So C is daughter of A and B. C @ D → C sister of D, so D is son of A and B. D # E → D husband of E. Hence E is wife of D (son of B), so E is daughter-in-law of B.
There are two married couples in a family of eight persons, P is the son of Q and brother of R. S is the daughter of M, who is married to R. T is aunt of S and mother of V. R's nephew W is the son of P and W's sister is V. How is V related to M?
Explanation:
R and M are a married couple. P and T are a married couple. V is the daughter of P and T. Since M is married to R (P's sibling), V is the niece of M.
