Calculation of Initial Amount and Creditor's Income

To determine the initial amount and the creditor's income from this operation, we need to use the formula for simple interest:

Simple Interest = Principal Amount x Interest Rate x Time

In this case, the principal amount is the initial sum, the interest rate is 25%, and the time is 1 year.

Let's calculate the initial amount and the creditor's income step by step:

1. Convert the interest rate from a percentage to a decimal: - Interest Rate = 25% = 0.25

2. Substitute the given values into the formula: - Simple Interest = Principal Amount x 0.25 x 1 year

3. Rearrange the formula to solve for the principal amount: - Principal Amount = Simple Interest / (Interest Rate x Time)

4. Substitute the given values into the rearranged formula: - Principal Amount = 20,000,000 / (0.25 x 1) = 80,000,000 rubles

5. Calculate the creditor's income by subtracting the initial amount from the final amount: - Creditor's Income = Final Amount - Principal Amount - Final Amount = Principal Amount + Creditor's Income - Creditor's Income = Final Amount - Principal Amount = 20,000,000 - 80,000,000 = -60,000,000 rubles

Therefore, the initial amount is 80,000,000 rubles, and the creditor's income from this operation is -60,000,000 rubles.
