It is 74 itself. Think of it like this: You have Rs. 9.7 with you and you want to buy as many chocolates as possible. In such a case, you can buy only 4 chocolates, as you are short of Rs. 0.3. Dividing 9.7 by 2 gives 4.85 that can be approximated to 5, which is wrong as 5 chocolates require Rs. 10 (you need Rs. 0.3 more). So, you can use the amount less than or equal to what you have with you.
