A factory applied to the bank for two kinds of loans, A and B, with an amount of 300,000 yuan, and it needs to pay interest of 40,000 yuan every year. The annual interest rate of loan A is 12%, and that of loan B is 1. The loan of Party A is RMB X million, and the loan of Party B is RMB 30-X..

12%*X is the interest of loan a, (30-X)* 14% is the interest of loan b, so:

12%*X+(30-X)* 14%=4

12% * X- 14% * X+ 14% * 30 = 4

2%*X= 14%*30-4

X=( 14%*30-4)/2%= 10

That is, the loan amount of Party A is 654.38 million yuan and the loan amount of Party B is 200,000 yuan.
