In a coded family language: 'A + B' = A is the mother of B; 'A - B' = A is the father of B; 'A $ B' = A is the son of B; 'A % B' = A is the sister of B; 'A / B' = A is the wife of B; 'A * B' = A is the husband of B. Which expression correctly shows that P is the son's wife of T? (i) T / B

Question

In a coded family language: 'A + B' = A is the mother of B; 'A - B' = A is the father of B; 'A $ B' = A is the son of B; 'A % B' = A is the sister of B; 'A / B' = A is the wife of B; 'A * B' = A is the husband of B. Which expression correctly shows that P is the son's wife of T? (i) T / B - K * P + O (ii) T + K * P + B % O (iii) K * P + B % T + P (iv) P + T * K + B % O

Accepted Answer

Only ii. In expression (ii): T+K means T is mother of K; K*P means K is husband of P (P is wife of K); thus P is the wife of T's son = son's wife of T. Expression (i) gives T as wife of B, not a mother; (iii) and (iv) don't establish the required relationship.
