ranging from Rs. 900 to Rs. 1200 and sold them at price ranging from Rs. 1050 to Rs. 1350. Find the maximum profit that can be earned by selling 15 such watches.Solution
Maximum profit will be earned when the cost price is least and selling price is maximum. Therefore, least cost price of 15 watches = 15 × 900 = Rs. 13500 Maximum selling price of 15 watches = 15 × 1350 = Rs. 20250 Therefore, maximum profit that can be earned = 20250 – 13500 = Rs. 6750
