A shopkeeper allows 25% discount on the marked price of an article and he suffered a loss of 15%. What will be the profit percent if the article is sold at marked price?

Accepted Answer

Let MP = 100. SP after 25% discount = 75. Since loss is 15%, CP = 75 / 0.85 = 1500/17. Selling at MP means profit = 100 - 1500/17 = 200/17. Profit % = (200/1500) * 100 = 13.33%.
