Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. P is B’s mother’s father.
‘A + B’ → ‘A is the brother of B’,
‘A - B’ → ‘A is the mother of B’,
‘A × B’ → ‘A is the father of B’ and
‘A ÷ B’ → ‘A is the son of B’.
Given expression: P × Q × R + D ÷ S - B;
P is the father of Q; Q is the father of R; R is the brother of D; D is the son of S and S is the mother of B.
From the family tree, we can see;
1. Q is B’s father → True
2. P is B’s mother’s father → False
3. R is B’s brother → True
4. R is P’s son’s son → True
Hence, the correct answer is P is B’s mother’s father.
