calculate interest rate per 100 for loan of 2,020 for 4 years and a repayment of 2,856

To calculate the interest rate per 100 for a loan of $2,020 for 4 years with a repayment of $2,856, we can use the following formula:

Interest Rate per 100 = (Total Repayment - Loan Amount) / (Loan Amount) * 100

Interest Rate per 100 = ($2,856 - $2,020) / $2,020 * 100
Interest Rate per 100 = $836 / $2,020 * 100
Interest Rate per 100 = 0.41386 * 100
Interest Rate per 100 = 41.38%

Therefore, the interest rate per 100 for the loan is 41.38%
