Attempted by 10 students.
Show answer & explanation
Correct answer: C
Explanation:
Meanings of the operators:
P ÷ Q means P is son of Q (P is male).
P × Q means P is sister of Q (P is female).
P + Q means P is brother of Q (P is male).
P - Q means P is mother of Q (P is female).
Evaluate the expression T - R + V ÷ S step by step:
T - R: T is mother of R.
R + V: R is brother of V, so R is male and R and V are siblings.
V ÷ S: V is son of S, so V is male and a child of S.
Since R and V are siblings and V is a child of S, R is also a child of S; therefore S is a parent of R.
T is the mother of R and S is the other parent of R, so S is male and the spouse of T. Hence S is the husband of T.
