Calculation of Interest on a Deposit

To calculate the interest earned on a deposit, we can use the formula:

Interest = Principal * Rate * Time

Where: - Principal is the initial amount deposited - Rate is the annual interest rate - Time is the number of years the deposit is held

Let's calculate the answers to the given questions:

1. The depositor opened a deposit account with a principal of 20,000 UAH at an annual interest rate of 12%. We need to find the interest earned after 3 years.

Using the formula mentioned above: - Principal = 20,000 UAH - Rate = 12% = 0.12 (in decimal form) - Time = 3 years

Interest = 20,000 * 0.12 * 3 = 7,200 UAH

Therefore, the depositor will receive a profit of 7,200 UAH after 3 years. [[1]]

2. The depositor wants to earn a profit of 820 UAH after 2 years with an annual interest rate of 5%. We need to find the amount that needs to be deposited.

Using the formula mentioned above: - Principal (unknown) = ? - Rate = 5% = 0.05 (in decimal form) - Time = 2 years - Interest = 820 UAH

Rearranging the formula to solve for Principal: Principal = Interest / (Rate * Time)

Substituting the given values: Principal = 820 / (0.05 * 2) = 820 / 0.1 = 8,200 UAH

Therefore, the depositor needs to deposit 8,200 UAH to earn a profit of 820 UAH after 2 years. [[2]]

Please note that these calculations assume that the interest is compounded annually. The actual interest calculation may vary depending on the specific terms and conditions of the deposit account.
