2. The minimum monthly repayment amount of China Merchants Bank's credit card is 10% and 10000 yuan, and the minimum repayment amount is 1000 yuan, and the rest will be paid next month. From the day when 10000 yuan is spent to the day when it is paid off, the "unpaid part" has to pay five ten thousandths of cyclic interest every day.

3. Calculation of interest: Cyclic interest = principal × five ten thousandths (interest) × days A (days from consumption date to current repayment date)+(paid principal) × five ten thousandths (interest) × days B (days from current repayment date to next billing date).
