A shopkeeper bought 3 different types of goods: 100
items at ₹50 each, 200 items at ₹40 each, and 50 items at ₹60 each. If he sold all items at ₹55 each, what is his percentage profit or loss?Solution
Cost price (CP) = (100 × 50) + (200 × 40) + (50 × 60) = 5000 + 8000 + 3000 = ₹16,000 Selling price (SP) = Total items × ₹55 = (100 + 200 + 50) × 55 = 350 × 55 = ₹19,250 Profit = SP - CP = 19,250 - 16,000 = ₹3,250 Profit percentage = (Profit / CP) × 100 = (3250 / 16,000) × 100 = 20.31% Correct answer: d) 20.3% profit
