Q. If 'A × B' means A is the mother of B, 'A ÷ B' means A is the brother of B, 'A − B' means A is the sister of B, what does 'P × Q − R' mean?
✅ Correct Answer: (A)
P is aunt of R
Explanation: Q − R means Q is sister of R, and P × Q means P is the mother of Q. So, P is the mother of R's sister → P is R's mother or aunt → since Q is sister, P is aunt.
