Answer 2

Calculation of Interest on Sergei Ivanovich's Bank Deposit

Sergei Ivanovich deposited 4000 rubles in a bank at an annual interest rate of 5%. We can calculate the amount he will have in his account after one, two, and three years by applying the interest rate to the initial deposit.

To calculate the amount after one year, we can use the formula:

Amount after one year = Initial deposit + (Initial deposit * Interest rate)

Substituting the values, we get:

Amount after one year = 4000 + (4000 * 0.05) = 4000 + 200 = 4200 rubles.

To calculate the amount after two years, we can use the same formula:

Amount after two years = Amount after one year + (Amount after one year * Interest rate)

Substituting the values, we get:

Amount after two years = 4200 + (4200 * 0.05) = 4200 + 210 = 4410 rubles.

To calculate the amount after three years, we can again use the same formula:

Amount after three years = Amount after two years + (Amount after two years * Interest rate)

Substituting the values, we get:

Amount after three years = 4410 + (4410 * 0.05) = 4410 + 220.5 = 4630.5 rubles.

Therefore, Sergei Ivanovich will have 4200 rubles in his account after one year, 4410 rubles after two years, and 4630.5 rubles after three years.

Please note that these calculations assume that the interest is compounded annually and that there are no additional deposits or withdrawals made during the specified time period.
