What number, when decreased by 15% become 45?

Given :

The number becomes 45, when it decreases by 15%.

To find :

We have to find the number.

Solution :

Let the number be 'x'.

 $x - 15% of x = 45$

$x - \frac{15}{100} x = 45$

$\frac{100x - 15x}{100} = 45$

$100x - 15x = 45 \times 100$

$85x = 4500$

$x = \frac{4500}{85}$

$x = 52.94$

The number is $52.94$
