The construction period of the construction project is 3 years, and the loans are evenly distributed in different years. The three-year loans are 3 million, 4 million and 5 million respectively, with an annual interest rate of 6%. Loan interest in the first year of construction = 1/2* loan amount in the current year * interest rate.

N+ 1 year loan interest during the construction period = total loan at the beginning of the year * interest rate+1/2* current loan amount * interest rate.

Loan interest in the first year of construction = 1/2*300*0.06=9.

Loan interest in the second year of construction = (300+9) * 0.06+1/2 * 400 * 0.06 = 30.54.

Loan interest for the second year of construction = (300+9+400+30.54) * 0.06+1/2 * 500 * 0.06 = 59.37.

Loan interest during construction period =9+30.54+59.37=98.9 1.
