2) 87,48:81*100=108 % (банк В)
Ответ: вкладчику выгоднее разместить деньги в банк В

Answer 2

Calculation of Interest Rates:

To determine which bank would be more profitable for the depositor, we need to calculate the interest rates offered by each bank. Let's denote the initial amount of money as P and the interest rate as r.

For Bank A, the initial amount is 67 rubles, and after one year, it becomes 73.03 rubles. We can set up the following equation:

P + P * r = 73.03 [[1]]

For Bank B, the initial amount is 81 rubles, and after one year, it becomes 87.48 rubles. We can set up the following equation:

P + P * r = 87.48 [[2]]

By solving these equations, we can find the interest rates for each bank.

Calculation Results:

After solving the equations, we find that the interest rate for Bank A is approximately 0.09 or 9%, and the interest rate for Bank B is approximately 0.08 or 8%.

Conclusion:

Based on the calculations, Bank A offers an interest rate of 9%, while Bank B offers an interest rate of 8%. Therefore, it would be more profitable for the depositor to place their money in Bank A.

Please note that these calculations are based on the given information and assumptions. It's always a good idea to consider other factors such as fees, terms and conditions, and the overall financial stability of the banks before making a final decision.
