Answer 2

Given:

A number becomes 150 when increased by 20%.

To find:

The number.

Solution:

The required number is 125.

To answer this question, we will follow the following steps:

Let the required number be x.

Now,

According to the question, we have

When x is increased by 20℅, it becomes 150.

So,

$x + 20\%x = 150$

This can be written as

$x + \frac{20}{100} x = 150$

On taking 100 as LCM, we get

$\frac{120x}{100} = 150$

$120x = 150 \times 100$

$x = \frac{150 \times 100}{120}$

$= 125$

Hence, the number is 125.
