When a person sold an article, his profit% is 65% of the selling price. If the cost price is increased by 80% and the selling price remains the same, then find decrement in the profit is what percent of the selling price of the article.
Let Selling price = 100 and Profit = 65 Then, CP = 100 – 65 = 35 Increased in CP = (80/100)×35 = 28 New CP = 35 + 28 = 63 Profit% = [(100 – 63)/100]×100 = 37%
