Question

If $30\%$ of a number is $75$ . Find the number.

Answer 1

It is given that $30\%$ of a number is $75$

So, let the number be $x$.

Then according to the question

$30\%$ of $x$ is $75$

i.e.,

$\begin{array}{rcl}\frac{30}{100}\times x& =& 75\\ & \Rightarrow & x=\frac{75\times 100}{30}\\ & \Rightarrow & x=250\end{array}$

Hence $30\%$ of $250$ is $75$.
