Question

вкладчик положил 1000 рублей в банк, годовая процентная ставка которого составляет 30%.Каким станет вклад через два года ,если банк начисляет сложные проценты

Answer 1

сколько прибыли получит вкладчик через 2 года

1000*0,3*2=600 руб

 

значит через 2 года у него станет вклад

1000+600=1600 руб

Answer 2

1000*30% = 1000/100=10 - это 1%

10*30=300 - процент за 1 год

300*2=600 - процент за 2 года

1000+600=1600рублей может забрать вкладчик через 2 года

 

 

 

 

 

 

Answer 3

Calculating Compound Interest on a Deposit

To calculate the value of the deposit after two years with a 30% annual compound interest rate, we can use the formula for compound interest:

Compound Interest Formula: \[ A = P \times \left(1 + \frac{r}{n}\right)^{nt} \] 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.

Given: - \(P = 1000\) rubles - \(r = 30\% = 0.30\) - \(n = 1\) (compounded annually) - \(t = 2\) years

Calculating the Amount: \[ A = 1000 \times \left(1 + \frac{0.30}{1}\right)^{1 \times 2} \]

Calculation

Using the given values, the calculation is as follows:

\[ A = 1000 \times (1 + 0.30)^{2} \]

Result

After calculating, the value of the deposit after two years with a 30% annual compound interest rate is approximately 3828.85 rubles.
