Question

Вкладчик положил на в банк 2800 р и написал поручение ежемесячно перечислять 5% от этой суммы за квартплату. Сколько денег останется на его счёте через 8 месяцев?

Answer 1

2800х5%=140
2800-140=2660 х5%= 133
2660-133=2527х5%= 126.35
2527-126.35= 2400.65х5%=120.03
2400.65-120.03=2280.62х5%= 114.03
2280.62-114.03=2166.59х5%= 108.33
2166.59-108.33=2058.26х5%=102.91
2058.26-102.91=1955.35х5%=97.77
1955.35-97.77=1857.58

Calculation of Remaining Money after 8 Months

To calculate the remaining money on the depositor's account after 8 months, we need to consider the initial deposit of 2800 rubles and the monthly transfer of 5% of this amount for quarterly payments.

Let's break down the calculation step by step:

1. Initial deposit: The depositor initially deposited 2800 rubles into the bank account.

2. Monthly transfer: The depositor instructed the bank to transfer 5% of the initial deposit for quarterly payments. This means that every month, 5% of 2800 rubles will be transferred from the account.

- Monthly transfer amount: 5% of 2800 rubles = 0.05 * 2800 rubles = 140 rubles.

3. Calculation for 8 months: We need to calculate the remaining money on the account after 8 months, considering the monthly transfers.

- Remaining money after 1 month: 2800 rubles - 140 rubles = 2660 rubles. - Remaining money after 2 months: 2660 rubles - 140 rubles = 2520 rubles. - Remaining money after 3 months: 2520 rubles - 140 rubles = 2380 rubles. - Remaining money after 4 months: 2380 rubles - 140 rubles = 2240 rubles. - Remaining money after 5 months: 2240 rubles - 140 rubles = 2100 rubles. - Remaining money after 6 months: 2100 rubles - 140 rubles = 1960 rubles. - Remaining money after 7 months: 1960 rubles - 140 rubles = 1820 rubles. - Remaining money after 8 months: 1820 rubles - 140 rubles = 1680 rubles.

Therefore, after 8 months, the depositor will have 1680 rubles remaining on their bank account.
