Question: A shopkeeper marks his goods 25% above the cost price. If he sells them at a discount of 10%, what is his profit percentage?
Options:
Correct Answer: 17.5%
Solution:
Let cost price = $100. Marked price = 100 + 25% of 100 = $125. Selling price after 10% discount = 125 - 10% of 125 = $112.5. Profit = 112.5 - 100 = $12.5. Profit percentage = (12.5 / 100) * 100 = 12.5%.
