When a person sold an article, his profit% is 70% 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.Solution
Let Selling price = 100 and Profit = 70 Then, CP = 100 – 70 = 30 Increased in CP = (80/100) × 30 = 24 New CP = 30 + 24 = 54 Profit% = [(100 – 54)/100] × 100 = 46%
