Answer & solution

Answer: Option A

Read the expression one symbol at a time.

P − Q: P is the son of Q.

Q ÷ R: Q is the brother of R, so Q is male.

R × S: R is the daughter of S.

S + T: S is the mother of T.

R is S's daughter and Q is R's brother, so Q is also a child of S. T is likewise a child of S.

So Q, R and T are brothers and sisters, with S their mother.

P is the son of Q, and Q is T's brother.

Therefore P is T's brother's son.
