If 20% of (A + B) = 30% of (A − B), then what percentage of B is equal to A?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 500%
Given that
If 20% of (A + B) = 30% of (A − B)
(20/100) * (A + B) = (30/100) * (A − B)
(A + B)/5 = 3 (A − B)/10
2A + 2B = 3A - 3B
A = 5B
Hence, A is 500% of B
