Answer 1

9090:15*100=60600 (тг) было положено

Answer 2

Calculation of the Initial Deposit Amount

To calculate the initial deposit amount, we can use the formula for calculating simple interest:

Interest = Principal * Rate * Time

In this case, the interest earned is 9090 tenge, the rate is 15% per year, and the time is 1 year. We need to find the principal, which represents the initial deposit amount.

Let's substitute the given values into the formula and solve for the principal:

9090 = Principal * 0.15 * 1

To find the principal, we can rearrange the equation:

Principal = 9090 / (0.15 * 1)

Calculating this, we find:

Principal = 60600 tenge

Therefore, the initial deposit amount was 60600 tenge.
