Show answer & explanation
Correct answer: D
Code Definitions
A + B: A is the son of B
A – B: A is the sister of B
A × B: A is the brother of B
A ÷ B: A is the mother of B
Step-by-Step Analysis
The expression is P ÷ Q × R – M + T:
P ÷ Q: P is the mother of Q.
Q × R: Q is the brother of R. Since P is the mother of Q, P is also the mother of R.
R – M: R is the sister of M. Since P is the mother of R, P is also the mother of M.
M + T: M is the son of T.
Conclusion
We now know that P is the mother of M and T is the parent (father) of M (since T must be male to be a father, and M is a son). Therefore, if P is the mother and T is the father of the same child (M), T is the husband of P.
