AI explanation

Let the cost price of one article be 1 rupee, making the cost price of 20 articles equal to 20 rupees. The selling price of 18 articles is also 20 rupees, so the selling price of one article is 20 divided by 18, which equals 10 divided by 9 rupees. Using the profit formula, the profit is ((10/9 minus 1) divided by 1) multiplied by 100. This results in a profit of 100 divided by 9 percent, which is 11(1/9) percent profit.
