Question

Find the whole quantity if.

$12\%$of it is $₹1080$

Answer 1

Let the whole quantity be $₹x$

So, according to the question

$12\%$ of $x$ is $₹1080$

Here ' of ' means multiplication and replace $\%$ sign by $\frac{1}{100}$

$$\begin{gathered} 12\times \frac{1}{100}\times x=1080 \\ \Rightarrow \frac{12x}{100}=1080 \\ \Rightarrow 12x=1080\times 100 \\ \Rightarrow x=\frac{1080\times 100}{12} \\ \Rightarrow x=\frac{12\times 9\times 10\times 100}{12}=9\times 10\times 100=9000 \end{gathered}$$

Hence, the whole quantity is $₹9000$.
