Answer 1

Прирост вклада: 1200 * 12/100 = 144 руб.
Основной вклад: 1200 руб.
Итоговая сумма: 1200 + 144 = 1344 руб.

Answer 2

Calculating Interest on the Deposit

To calculate the amount of money on the account after one year with a 12% annual interest rate on a deposit of 1200 rubles, we can use the formula for calculating compound interest:

A = P(1 + r/n)^(nt)

Where: - A = the amount of money accumulated after n years, including interest. - P = the principal amount (initial deposit). - r = the annual interest rate (in decimal). - n = the number of times that interest is compounded per year. - t = time the money is invested for in years.

In this case, the interest is compounded annually, so n = 1 and t = 1 year. The annual interest rate is 12%, which in decimal form is 0.12.

Calculation

Using the given values: - P = 1200 - r = 0.12 - n = 1 - t = 1

We can calculate the amount of money on the account after one year.

Result

Plugging the values into the formula:

A = 1200(1 + 0.12/1)^(1*1)

A ≈ 1344

So, the amount of money on the account after one year, with only the interest being added, will be approximately 1344 rubles.

This calculation assumes that no other transactions or changes occur on the account during the year.
