Question

СРОЧНО РЕШИТЕ ЗАДАЧУ ДАЮ 30 БАЛЛОВ Банк выплачивает ежегодно 3% от суммы вклада. Сколько денег получит вкладчик через 2 года 7 месяцев, если первоначальная сумма вклада составляла 2 000 рублей?

Answer 1

7 месяцев = 7/12 года
В конце первого года 2000+2000*0,03 = 2000+60 = 2060 руб.
В конце второго года 2060+2060*0,03 = 2060+61,8 = 2121,8 руб.
Через 2 года 7 месяцев 2121,8+2121,8*0,03*7/12 = 2121,8+37,13 = 2158,93 руб.

Answer 2

Calculation of Interest on Deposit

To calculate the amount of money the depositor will receive after 2 years and 7 months with an initial deposit of 2,000 rubles and an annual interest rate of 3%, we need to determine the interest earned for each year and month.

1. Calculation of interest for 2 years: - The interest earned for 2 years can be calculated by multiplying the initial deposit by the annual interest rate and then multiplying it by 2. - Interest for 2 years = 2,000 * 0.03 * 2 = 120 rubles.

2. Calculation of interest for 7 months: - The interest earned for 7 months can be calculated by multiplying the initial deposit by the monthly interest rate and then multiplying it by 7. - The monthly interest rate can be calculated by dividing the annual interest rate by 12. - Monthly interest rate = 0.03 / 12 = 0.0025. - Interest for 7 months = 2,000 * 0.0025 * 7 = 35 rubles.

3. Total amount received: - To calculate the total amount received, we need to add the initial deposit to the interest earned for 2 years and 7 months. - Total amount received = 2,000 + 120 + 35 = 2,155 rubles.

Therefore, the depositor will receive 2,155 rubles after 2 years and 7 months with an initial deposit of 2,000 rubles and an annual interest rate of 3%.

Please note that the above calculation assumes that the interest is compounded annually. If the interest is compounded more frequently (e.g., quarterly or monthly), the calculation may differ.
