If the income tax is increased by 17% then the net income is decreased by 3%. Find the rate of income tax.

15%

Income = net income + tax

ATQ,         Tax × \(\frac{17}{100}\) = Net income ×  \(\frac{3}{100}\)

                          \(\frac{Tax}{Net income}\) = \(\frac{3}{17}\)

                                                    Income = 20

                  Rate if income tax = \(\frac{3}{20}\) × 100 = 15 %
