As it is not mentioned above whether the 9% interest rate is the annual interest rate or the monthly interest rate, there will be two situations, the specific analysis is as follows:

First of all, it should be clear that "profit" is an interest rate unit, with annual interest rate 1% and monthly interest rate 1%.

1. If the loan interest rate is 9% per year, the interest will be repaid 18000 yuan one year, and the principal will be repaid 2 18000 yuan one year later;

2. If the interest rate of your loan is 9% per month, you have to pay back the interest of 2 1600 yuan one year, plus the principal, and it will be 22 1600 yuan one year later. (generally refers to the monthly interest rate)
