If books bought at prices ranging from Rs. 150 to Rs. 300 are sold at prices ranging from Rs. 250 to Rs 350, what is the greatest possible profit that might be made in selling 15 books ?  Choose the correct choice from the following options
A) Rs. 2500
B) Rs. 3000
C) Rs. 3500
D) Rs. 3200
E) Rs. 3600
The greatest profit is possible only if the cost price of the books are minimum and selling prices are maximum.   Let lowest cost price of the 15 books = 150*15 = Rs. 2,250   Maximum selling price of 15 books = 350 *15 = Rs. 5,250   So, maximum profit = 5250 - 2250 = Rs. 3,000   ANSWER : OPTION Rs. 3000
