Aug 14, 2018

$186$ books

#### Explanation:

Think of $120$ as 100%

Now if you increase something by 55%, then basically you want to find what 155% of $120$ is because of 100+55=155%

To find what 155% of $120$ is, you can write it as

120=100%
x=155%

So,
$x = 120 \times \frac{155}{100}$

$x = 186$
