# By selling an article at 80% of its marked price, a merchant makes a loss of 12%. What % profit will the merchant make if the article is sold at 95% of its marked price?

Since they sold it at 80% of the marked price and it was a loss of 12% that means that the price they bought it from the supplier would be 92% the marked cost. And if it is sold at 95% the marked price then it would be a 3% profit since 95%-92%=3%.
