Question

Find a number that becomes 585 when increased by 8 1/3%​​

Answer 1

Let the number be x

Given that x is increased by 15% gives 161

`⇒ (x + 15)/(100 * x) = 161 \\ = (115)/(100) * x = 161 \\⇒ x = 140`

Answer 2

540

Explanation:

Increasing by 8 1/3% is basically multiplying by 108.33...%

therefore, you get:

585=108.33333333333% * x

x=540
