Select.
A) Rs. 1650 B) Rs. 3000 C) Rs. 1521 D) Rs. 1400 E) Rs. 1560
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 13 books = 98*13 = Rs. 1,274   Maximum selling price of 13 books = 215 *13 = Rs. 2,795   So, maximum profit = 2795 - 1274 = Rs. 1,521   ANSWER : OPTION Rs. 1521
