Find the profit or loss percentage in the following cases. (i) Cost price=Rs. 500, marked price=Rs. 700 and ciscount=Rs. 250. (ii) Selling price=Rs. 1200 and profit=Rs. 200.

Answer» Correct Answer - (i)`10%" loss "" "(ii) 20%" profit"`
(i) Cost price (CP)=Rs. 500
Marked price (MP)=Rs. 700
Discount =Rs. 250
`SP=MP-"discount"`
`=Rs.(700-250)=450`
Here,`SPltCP`, there is a loss.
`Loss=CP-SP=Rs.(500-450)=Rs. 50`
`Loss%=("Loss")/(CP)xx100%`
`=(50)/(500)xx100%=10%`
(ii) SP=Rs. 1200
Profit=Rs. 200
`CP=SP-"Profit"=Rs.(1200-200)=Rs. 1000`
`"Profit"%=("Profit")/(CP)xx100%`
`=(200)/(1000)xx100%=20%`
