ranging from Rs. 1500 to Rs. 1800 and sold them at price ranging from Rs. 1650 to Rs. 1950. Find the maximum profit that can be earned by selling 10 such watches.Solution
Maximum profit will be earned when the cost price is least and selling price is maximum. Therefore, least cost price of 10 watches = 10 times; 1500 = Rs. 15000 Maximum selling price of 10 watches = 1950 times; 10 = Rs. 19500 Therefore, maximum profit that can be earned = 19500 ndash; 15000 = Rs. 4500
