Question
Cost price of a bag is Rs.750. The shopkeeper marked it
80% above the cost price and sold it after giving a discount of 20%. If the shopkeeper had sold it at a profit of 50%, then find the difference between original and new selling price of a bag.Solution
Original selling price of a bag = (180/100) × (80/100) × 750 = Rs.1080 New selling price of a bag = (150/100) × 750 = Rs.1125 Required difference = 1125 – 1080 = Rs.45
