In a certain code language,
‘A + B’ means ‘A is the mother of B’,
‘A – B’ means ‘A is the father of B’,
‘A $ B’ means ‘A is the son of B’,
‘A % B’ means ‘A is the sister of B’,
‘A / B’ means ‘A is the wife of B’ and
‘A = B’ means ‘A is the brother of B’.
Which of the following means A is the daughter of K?
- A.
A + K / J – P = D
- B.
J % P = K + A = D
- C.
K + A / P – D % J
- D.
D + K = A / P – J

Show answer & explanation
Correct answer: C
We need an expression where A is the daughter of K. This requires A to be female (meaning she must be a wife or a sister) and K to be a parent (mother or father) of A.
Option 1 (A + K / J - P = D): This expression translates to: A is the mother of K. This does not make A the daughter of K.
Option 2 (J % P = K + A = D): The solution text mentions this expression represents the relationship, but let's trace it: J is the sister of P, P is the brother of K, K is the mother of A, A is the brother of D. In this scenario, K is the mother of A. Since A is the brother of D, A is K's son, not daughter.
Option 3 (K + A / P - D % J): Let's trace this:
K + A: K is the mother of A.
A / P: A is the wife of P.
Because A is the wife of P, A is female. Because K is the mother of A, A is the daughter of K.
This expression correctly satisfies the condition.
