If a commission of 10\% is given on the written price of an article, the gain is 20\%. If the commission is increased to 20\%, the gain is
(a)$6 \frac{2}{3} \%$
(b)$7 \frac{1}{4} \%$
(c)$12 \frac{1}{2} \%$
(d)$13 \frac{1}{3} \%$
Answer
Explanation
Let the marked price be ₹ 100. Then, S.P. $=₹\left(\frac{90}{100} \times 100\right)=₹ 90$. Gain $=20 \%$. $$\therefore \quad \text { C.P. }=₹\left(\frac{100}{120} \times 90\right)=₹ 75 .$$ New commission $=₹ 20$; New S.P. $=₹ 80$. $$\therefore \quad \text { New Profit }=\left(\frac{5}{75} \times 100\right) \%=6 \frac{2}{3} \% .$$
