a shopkeeper sold an article offering a discount of 5 % and earned a profit of 31.1 %. what would have been the percentage of profit earned if no discount had been offered?
subtract(divide(multiply(add(const_100, 31.1), const_100), subtract(const_100, 5)), const_100)
"giving no discount to customer implies selling the product on printed price . suppose the cost price of the article is 100 . then printed price = 100 ã — ( 100 + 31.1 ) / ( 100 â ˆ ’ 5 ) = 138 hence , required % profit = 138 â € “ 100 = 38 % answer a"
