Percentage Practice Test 8 with solutions

26% of income tax =$\frac{2}{3}$% of the net income
∴ Income tax $=\left[\frac{2}{3}\times \frac{100}{26}\right]\%$ of the net income $=\frac{100}{39}\%$ of the net income
Let net income = Rs. 3900
∴ Income tax = $3900\times \frac{100}{39\times 100}=\mathrm{Rs}.100$
⇒ Gross income = Rs. 3900 + Rs. 100 = Rs. 4000
∴ Rate % of income tax $=\left(\frac{100}{4000}\times 100\right)\%=2\frac{1}{2}\%$
