Problem Analysis

To solve this problem, we need to find the original salary before a 13% tax was deducted. We are given that the salary after the tax deduction is 20,880 rubles.

Solution

Let's assume the original salary before the tax deduction is x rubles.

We know that the tax deduction is 13% of the original salary. Therefore, the tax amount deducted can be calculated as 0.13 * x.

The salary after the tax deduction is the original salary minus the tax amount deducted. So we have the equation:

x - 0.13 * x = 20,880

Simplifying the equation, we get:

0.87 * x = 20,880

To find the value of x, we can divide both sides of the equation by 0.87:

x = 20,880 / 0.87

Now we can calculate the value of x:

x ≈ 24,000

Therefore, the original salary before the tax deduction was approximately 24,000 rubles.

Answer

The original salary before the 13% tax deduction was approximately 24,000 rubles.
