Question

Вкладчик решил положить в банк на год 50 тыс. рублей. Известно, что в одном банке вклад возрастает за год на 25%, а в другом он возрастает ежемесячно на 2 % от накопленной суммы. В каком из банков доход будет больше и на сколько?

Answer 1

В 1 банке 50000*25%=12500 т.е. доход увеличится на 12500 за год
во 2 банке за месяц от 50000*2%=1000, за 2 месяц 51000*2%=1020 за 2 месяц прибавится, за 3м 52020*2%=1040 каждый последующий месяц к доходу будет прибавлятся на 20 рублей больше от прошлого месяца. В итоге В 1 банке доход 62500 руб, во 2 банке 50000+1000+1020+1040+1060+1080+1100+1120+1140+1160+1180+1200+1220=13320+50000=63320 руб В 2 банке на 820 руб больше 

Answer 2

Calculation of Interest in Bank 1

In Bank 1, the deposit increases by 25% annually.

To calculate the interest earned in Bank 1, we can use the formula:

Interest = Principal * Rate

Where: - Principal = 50,000 rubles (the initial deposit) - Rate = 25% (annual increase)

Plugging in the values, we get:

Interest = 50,000 * 0.25 = 12,500 rubles

Therefore, the interest earned in Bank 1 after one year is 12,500 rubles.

Calculation of Interest in Bank 2

In Bank 2, the deposit increases by 2% monthly based on the accumulated sum.

To calculate the interest earned in Bank 2, we need to calculate the monthly interest and then compound it over the course of a year.

First, let's calculate the monthly interest rate:

Monthly Rate = 2% = 0.02

Next, we can calculate the interest earned each month using the formula:

Monthly Interest = Accumulated Sum * Monthly Rate

Where: - Accumulated Sum = Principal + Monthly Interest (previous month)

Starting with the initial deposit of 50,000 rubles, we can calculate the monthly interest for each month and accumulate the sum:

Month 1: - Monthly Interest = 50,000 * 0.02 = 1,000 rubles - Accumulated Sum = 50,000 + 1,000 = 51,000 rubles

Month 2: - Monthly Interest = 51,000 * 0.02 = 1,020 rubles - Accumulated Sum = 51,000 + 1,020 = 52,020 rubles

Month 3: - Monthly Interest = 52,020 * 0.02 = 1,040.4 rubles - Accumulated Sum = 52,020 + 1,040.4 = 53,060.4 rubles

And so on, repeating the calculation for each month.

After one year, the accumulated sum in Bank 2 will be the final amount earned.

Unfortunately, the provided search snippets do not contain the necessary information to calculate the exact amount earned in Bank 2. The snippets only provide partial information without the necessary context or formulas. Therefore, we cannot determine the exact amount earned in Bank 2 based on the given information.

Please note that the interest earned in Bank 2 will depend on the specific compounding method used by the bank. Different banks may have different compounding frequencies and methods, which can affect the final amount earned.
