Question
When a person sold an article, his profit% is 60% of the
selling price. If the cost price is increased by 80% and the selling price remains the same, then decrement in the profit is what percent of the selling price of the article.Solution
Let Selling price = 100 and Profit = 60 Then, CP = 100 – 60 = 40 Increased in CP = (80/100) × 40 = 32 New CP = 40 + 32 = 72 Profit% = [(100 – 72)/100] × 100 = 28% Decrement in Profit = 60% - 28% = 32%
