A seller purchased certain number of watches at prices
ranging from Rs. 1000 to Rs. 1300 and sold them at price ranging from Rs. 1150 to Rs. 1450. Find the maximum profit that can be earned by selling 13 such watches.Solution
Maximum profit will be earned when the cost price is least and selling price is maximum. Therefore, least cost price of 13 watches = 13 × 1000 = Rs. 13000 Maximum selling price of 13 watches = 13 × 1450 = Rs. 18850 Therefore, maximum profit that can be earned = 18850– 13000 = Rs. 5850
