If b exceeds 500, the tax rate is 5% according to the table, and 500*5%=25.
C's tax is 165. According to the table, it can be calculated that it does not exceed 500, the maximum is 25500-2000, and the maximum is 25+ 150= 175, so its amount must be between 500-2000, 165-25 = 145.
Let the tax rate of Lily be X, then Wang Juan is X+ 100, because the total amount is 25, so its tax rate must be 5%.
X*5%+(X+ 100)*5%=25
X=200 X+ 100=300
So the salary =300+2000=2300 Li 200+2000=2200.
