The positive solution is as follows:
Solution: (1) If the loan is given to China Construction Bank and the annual repayment is X yuan, then a * * * repayment 10X, a * * * repayment is equal to the principal plus interest, then there is it.
10X = 10+ 10X 5%+( 10-X)5%+( 10-2X)5%+( 10-3X)5%+……+( 10-9X)5%
The solution is x≈ 12245 (yuan).
