If P + Q means P is the brother of Q
P × Q means P is the mother of Q
P ÷ Q means P is the father of Q
P - Q means P is the sister of Q.
If equation given A × B ÷ C - D + E - F then how is E related to A?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Son's daughter.
Given the equation: A × B ÷ C - D + E - F → A is the mother of B, B is the father of C, C is the sister of D, D is the brother of E and E is the sister of F.
