Given the tax Little Hi paid, do you know his salary this month?
Line 1: M, the tax Little Hi paid. (1 <= M <= 5,000,000)
Line 1: Little Hi‘s salary. The number should be rounded dowm to the nearest integer.
Little Hi‘s salary is 15692 yuan. The tax is calculated below:
The income amount taxable is 15692 - 3500 = 12192 yuan.
That part of income of 1500 or less: 1500 * 3% = 45 yuan.
That part of income in excess of 1,500 to 4,500 yuan: 3000 * 10% = 300 yuan.
That part of income in excess of 4,500 to 9,000 yuan: 4500 * 20% = 900 yuan.
That part of income in excess of 9,000 to 35,000 yuan: (12192 - 9000) * 25% = 798 yuan.
Total tax is 45 + 300 + 900 + 798 = 2043 yuan.
