Question

What is $30$ percent of $90$?

• A. $30$
• B. $15$
• C. $27$
• D. $45$

Answer 1

The correct option is C

$27$

The explanation for the correct option:

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

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

We have to find $30\%$ of.$90$

$$\begin{gathered} \therefore 30\%\mathrm{of}90=\frac{30}{100}\times 90 \\ \Rightarrow =3\times 9 \\ \Rightarrow =27 \end{gathered}$$

Hence, option C is the correct option.
