Explanation:

Alright, let's break down the statements and the options, one by one, without the fluff.

Symbol Meanings

- @ ? ‘and’ (so P @ Q means ‘P and Q’)

- % ? ‘Q is wife of P’ (so P % Q means Q is P’s wife)

- # ? ‘Q is daughter of P’ (Q is daughter, P is parent)

- * ? ‘P is younger than Q’

- $ ? ‘Q is parent of P’

- & ? ‘P and Q are siblings’

The Relations

- R*S: R is younger than S

- S#T: T is daughter of S (S is parent, T is daughter)

- T&V: T and V are siblings

- S&R$P@Q:

- S and R

- R is parent of P

- P and Q

- T*V: T is younger than V

- U%S: S is wife of U

- P%Q: Q is wife of P

- X&W$R:

- X and W

- W is parent of R

Key Point

- T’s age is 20 years.

- T and V are siblings.

- T is younger than V.

The Options

- 13: V would be younger than T (impossible)

- 22: Makes sense (V could be older)

- 18: V would be younger than T (impossible)

- 15: V would be younger than T (impossible)

What this really means is:

Only 22 fits because V must be older than T (who is 20). Anything less than or equal to 20 is ruled out.

Correct Answer:

Option:2, 22

- This makes logical sense, V is the only sibling who can be older than 20 (T).

- All the other options have V younger than 20, which contradicts the direct statement that T is younger than V. Easy win.
