Question

What is $30\%$ of $120$?

Answer 1

Percentage:

$a\%$ of a number $b$ is computed as;

$a\%\mathrm{of}b=b\times \frac{a}{100}$

We have to find $30\%$ of $120$.

$$\begin{gathered} \therefore 30\%\mathrm{of}120=120\times \frac{30}{100} \\ \Rightarrow =\frac{3600}{100} \\ \Rightarrow =36 \end{gathered}$$

Hence, the required value is $36$.
