Question
A shopkeeper purchased 80 identical articles for a total
of ₹20,000. He sold 60% of these items at a 25% profit and the remaining at a 15% loss. Calculate the overall profit or loss percentage on the entire transaction.Solution
Cost of 1 article = 20,000/80 = 250 Cost of 60% (48) articles = 250×48 = 12000 Cost of 40% (32) articles = 250×32 = 8000 Selling price of 60% articles = 125% of 12,000 = 15,000 Selling price of 40% articles = 85% of 8,000 = 6,800 Total selling price = 15,000+6,800 = 21,800 = 9%
