Question

$25\%$of what number is $5$?

Answer 1

Find the number:

Suppose $x$ be the required number.

From the given problem we have,

$25\%ofx=5$ .

$$\begin{gathered} \Rightarrow \frac{25}{100}·x=5 \\ \Rightarrow 0.25x=5 \\ \Rightarrow x=\frac{5}{0.25}\left[\mathrm{Divide}\mathrm{both}\mathrm{sides}\mathrm{by}0.25\right] \\ \therefore x=20 \end{gathered}$$

Hence $25\%$of $20$ is $5$.
