Question

$40\%$ of a number is $800$, Find the number?

Answer 1

Let the unknown number be $\mathrm{p}$.

Given, $40\%\mathrm{of}\mathrm{p}=800$

$\Rightarrow$ $\frac{40}{100}\times p=800$

$\Rightarrow$$\mathrm{p}=800\times \frac{100}{40}$

$\Rightarrow \mathrm{p}=2000.$

Hence, the required number is $2000$.
