Answer 2

Given:

A number increased by 20% gives 42.

To find:

The number.

Solution:

Let the required number be x.

So, according to the question, the number is increased by 20℅ and then gives 42.

Thus, we have,

$x + 20\% of x = 42$

$x + \frac{20x}{100} = 42$

On taking LCM, we have

$\frac{100x + 20x}{100} = 42$

$\frac{120x}{100} = 42$

On simplifying, we have

$\frac{6x}{5} = 42$

$6x = 210$

$x = \frac{210}{6}$

$x = 35$

Hence, the number which gives 42 when increased by 20% is 35.
