A seller purchased certain number of watches at prices
ranging from Rs. 2000 to Rs. 2300 and sold them at price ranging from Rs. 2150 to Rs. 2450. Find the maximum profit that can be earned by selling 4 such watches.Solution
Maximum profit will be earned when the cost price is least and selling price is maximum. Therefore, least cost price of 4 watches = 4 × 2000 = Rs. 8000 Maximum selling price of 4 watches = 4 × 3000 = Rs. 12000 Therefore, maximum profit that can be earned = 12000 – 8000 = Rs. 4000
