Question
A shopkeeper marks an article 50% above the cost price
and then gives two successive discounts of 20% and 10%. What is his overall profit or loss percentage?Solution
Let the cost price be ₹100. Marked price = ₹150. After the first discount of 20%, the price becomes ₹150 × 0.80 = ₹120. After the second discount of 10%, the price becomes ₹120 × 0.90 = ₹108. Profit percentage = ((108 - 100) / 100) × 100 = 8%.
