Ravi purchased an old scooter for Rs. 12000 and spent Rs.2850 on its overhauling. Then he sold it to his friend for Rs. 13860. How much percent did he gain or lose?
Cost price =Rs. 12000, overhead charges =Rs. 2850
∴ Total cost price =Rs(12000+2850)=Rs. 14850
Selling Price =Rs. 13860
Selling Price < Cost Price → Loss
∴ Loss = Cost price − Selling price
⇒ Loss =Rs. (14850−13860)=Rs. 990
Loss percent =LossCost Price×100%
Loss percent =99014850×100%=6.67%
So, Ravi incurred a loss of 6.67%.
