## Text Solution

What is Known?

The amont of money that Meet saved from her salary and the percentage of her salary the saving is equal to.

What is Unknown?

Salary of Meeta.

Reasoning:

Assume the salary to be $$A.$$ Since $$10 \%$$ of $$A$$ is known, $$100 \%$$ of $$A$$ (total salary) of Meeta can be obtained.

Steps:

Let the total salary be Rs $$A.$$ If $$10 \%$$ of$$A$$ is $$400$$

Thus,

\begin{align} \frac{{10}}{{100}} \times A = 400\end{align}

Or

\begin{align} A = 400 \times \frac{{100}}{{10}}\\= 4000 \end{align}

Thus, the total salary is $$\rm Rs. 4000$$
