cost price and sold at a discount of ____%. The profit earned by the retailer is ____%. The values given in which of the following options will fill the blanks in the same order to make the statement true? I. 24, 6.4Â II. 20, 12Â III. 15, 19 Â IV. 18, 14.8Solution
ATQ, Let the cost price of the item coffee beans be Rs. ‘a’. Marked price of the item = Rs. 1.4a From option I: S.P of the article = 1.4a × 0.76 = Rs. 1.064a Profit percentage = 6.4% So, option I can be the answer. From option II: S.P of the article = 1.4a × 0.8 = Rs. 1.12a Profit percentage = 12% So, option II can be the answer. From option III: S.P of the article = 1.4a × 0.85 = Rs. 1.19a Profit percentage = 19% So, option III can be the answer. From option IV: S.P of the article = 1.4a × 0.82 = Rs. 1.148a Profit percentage = 14.8% So, option IV can be the answer.
