Question : 20

If 15% of (A + B) = 25% of (A – B), then what per cent of B is equal to A?

a) 200%

b) 400%

c) 10%

d) 60%

Answer: (b)

15% of (A + B) = 25% of (A – B)

$15/100(A + B) = 25/100(A - B)$

15 (A + B) = 25 (A – B)

15 A + 15 B = 25A – 25 B

10 A = 40 B

A = 4 B

Now, let x% of B is equal to A

$x/100×B =A ⇒ x/100×B =4B$

x = 400%
