Question
If the income tax is increased by 18% the net income is
reduced by 3%. Find the rate of income tax?Solution
Income tax  x (18 /100)  = Net income x (3/100) Income tax / net income = 3 / 18 Total income = Net income + Income tax Total income = 18 + 3 = 21 Rate of income tax = (3/21) x 100 = 14.28 %
