Question
When a person sold an article, his profit% is 40% of the
selling price. If the cost price is increased by 50% 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 = 40 Then, CP = 100 – 40 = 60 Increased in CP = (50/100) × 60 = 30 New CP = 60 + 30 = 90 Decrement in Profit = (100-60) - (100-90) = 30 Profit% = [(100 – 30)/100] × 100 = 70%
