A shopkeeper marks his goods 50% above the cost price but allows his customers a discount of 20% on the marked price. What is his actual profit if selling price is rupees 6000?
Let the cost price be 100x. Marked price = (100 + 50) % of 100x = 150x Selling price after 20% discount = 150x × 0.8 = 120x 120x = 6000 x = 50 Profit = 120x – 100x = 20x = 1000
