If the selling price of an article is increased by 20%, the profit becomes three times the original profit. What was the original profit percentage? MCQ with Answer and Explanation

Let Cost Price = 100 and initial Selling Price = x. Initial profit = x - 100. New Selling Price = 1.20x. New profit = 1.20x - 100. 1.20x - 100 = 3 * (x - 100). 1.20x - 100 = 3x - 300. 1.8x = 200. x = 111.11. Original profit = 11.11. Profit percentage = 11.11%.
