Question

12.5% of what number is 20

Answer 1

12.5 / 100 = 20 / X
multiply 100 x 10 to get 2000
multiply 12.5 x X to get 12.5X
divide both 2000 and 12.5X by 12.5 to get 2000 / 12.5 = X
2000 / 12.5 = 160 therefore X = 160
check your answer by multiplying 0.125 by 160 to get 20

Answer 2

Answer:

160

Step-by-step explanation:

Let x be the unknown number,

∵ 12.5% of x = $\frac{12.5x}{100}$

According to the question,

$\frac{12.5x}{100}=20$

$12.5x = 2000$    ( By cross multiplication )

$x=\frac{2000}{12.5}$

$\implies x = 160$

Therefore, 12.5% of 160 is 20.
