If the ratio of marked price and selling price is 11 : 10, then what is the discount percentage?1). 11.112). 17.283). 12.54). 9.09

Answer»

MARKED PRICE/selling price = 11/10

⇒ Selling price/Marked price = 10/11

∴ Discount % = {(MP - SP)/MP} × 100 = {1 - (SP/MP)} × 100 = {1 - (10/11)} × 100 = 9.09%
