Question

The difference between a hundred and a number is four times that number.

what does this equal to?

Answer 1

Explanation:

Let the number be x

Four time that number = 4x

The difference between a hundred and a number = 100 -x

100- x = 4x

100 = x + 4x

100 = 5x

5x = 100

x = 100/5 = 20
