Write a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is RS4,000; for married people, the standard exemption is RS7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is:  Between RS0 and RS15,000, the tax rate is 15%.  Between RS15,001 and RS40,000, the tax is RS2,250 plus 25% of the taxable income over RS15,000.  Over RS40,000, the tax is RS8,460 plus 35% of the taxable income over RS40,000
