Answer 2

Calculation of Nikolay Petrovich's Salary

To calculate Nikolay Petrovich's salary, we need to determine the amount before the income tax deduction. We know that the income tax rate is 13% of the salary, and after the deduction, Nikolay Petrovich received 20880 rubles.

Let's denote Nikolay Petrovich's salary before the income tax deduction as X.

The equation to calculate Nikolay Petrovich's salary after the income tax deduction is as follows:

X - (13% of X) = 20880 rubles

To solve this equation, we can express 13% as a decimal by dividing it by 100:

X - (0.13 * X) = 20880 rubles

Simplifying the equation:

0.87 * X = 20880 rubles

Now, we can solve for X by dividing both sides of the equation by 0.87:

X = 20880 rubles / 0.87

Calculating the value of X:

X ≈ 24000 rubles

Therefore, Nikolay Petrovich's salary before the income tax deduction is approximately 24000 rubles.

Please note that this calculation assumes that the income tax is the only deduction from Nikolay Petrovich's salary. Other deductions, such as social security contributions or healthcare contributions, are not considered in this calculation.
