From (1900+A) x0.05% per day to the second repayment date, the accumulated interest is b; The second repayment is1900+a+b a+b.

how much is it? Do the math yourself.

Interest b is accumulated to the second repayment date. In the previous bill, only the accumulated interest up to the bill date will be displayed, and the accumulated interest from the bill date to the repayment date will not be displayed. So you have to estimate for yourself that it is more than what is shown on the bill, and you can't repay it according to the figures shown on the bill, otherwise the interest will be endless.
