Given Data:

Salary of an officer increased 10 % every year = 48400

To Find:

Calculate the Original Salary of an officer:

Step –by- Step Explanation:

Step 1:

Let us assume original salary was X.

Step 2:

Salaries in second year, after 1st increment would be 1.1X.

Step 3:

Salary in third year, after 2nd increment would be $1.1\times1.1X=1.21X.$

Step 4:

Now, we know salary in third year is rs 48400.
