Ex 8.2 | Question 9

## 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 \(\rm Rs. 4000\)
