The difference of two numbers is 20% of the larger number. If the smaller number is 40, then find the larger number.

Correct option is D

Given:

The difference of two numbers is 20% of the larger number, if the smaller number is 40

Calculation

Let the large number be x

Then $$x - 40 = \frac{20x}{100}$$​​

 x - $$\frac{x}{5}$$​ = 40

 x = 50

Hence, x = 50
