RS. 50.Profit percentage = 25%CalculationLet cost price be 100X.Hence, marked price = 150% of 100x = 150xNow, selling price = MP - Discount = 150X - 50 ---- (1)Also, if profit is 25%, then selling price = 125% of CP = 125xFrom (1), we get150x - 50 = 125x⇒ 25x = 50⇒ X = 2∴ Selling price = 125x = 125 × 2 = Rs. 250.
