Answer» Correct Answer - Option 4 : 12.63% Given: CP = Rs. 3200 Spent on repair = Rs. 600 SP = Rs. 4280 Where CP = Cost price, SP = Selling price Formula used: \({\rm{Profit\% \;}} = {\rm{\;}}\frac{{{\rm{SP\;}} - {\rm{\;CP}}}}{{{\rm{CP}}}}{\rm{\;}} × {\rm{\;}}100\) Calculation: New CP = Rs. (3200 + 600) = Rs. 3800 \({\rm{Profit\% \;}} = {\rm{\;}}\frac{{4280{\rm{\;}} - {\rm{\;}}3800}}{{3800}}{\rm{\;}} × {\rm{\;}}100\) ⇒ 480/38 × 100 ⇒ 12.63% ∴ profit percentage is 12.63% |
