    Anand marks up the price of an article by 50% and then allows a discount of 20% and sells it to Balaji. Balaji sells it for Rs. 20 more than what he purchased for, this S.P is 30% more than the original C.P of the article. Then Balaji's profit % is

    A) 7.5%                            

    B) 6.66%

    C) 8.33%                          

    D) 9%

    Correct Answer: C

    Solution :

    For Anand, Cost price = Rs. \[x\] Marked price = Rs. \[\frac{3}{2}x\] Selling price \[=\frac{3x}{2}\times \frac{80}{100}=Rs.\frac{6x}{5}\] For Balaji, Cost price =\[~Rs.=\frac{6x}{5}\] Selling price = Rs. \[\left( \frac{6x}{5}+20 \right)\] \[\therefore \] \[\frac{6x}{5}+20=\frac{x\times 130}{100}\] \[\Rightarrow \frac{13x}{10}-\frac{6x}{5}=20\] \[\Rightarrow \frac{13x-12x}{10}=20\] \[\Rightarrow \frac{x}{10}=20\] \[\Rightarrow x=Rs.\,\,200\] \[\therefore \]Required gain percent \[=\frac{20}{\frac{6x}{5}}\times 100\] \[=\frac{20\times 5\times 100}{6\times 200}=\frac{25}{3}=8.33%\]
