‘A & B’ means ‘A is the brother of B’,
‘A × B’ means ‘A is the sister of B’,
‘A – B’ means ‘A is the father of B’.

Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Mother’s mother.
If ‘A × Z + P & R ÷ Q – S’ → A is the sister of Z, Z is the mother of P, P is the brother of R, R is the wife of Q and Q is the father of S.

Thus, Z is the Mother’s mother of S.
