c) 500 is the correct

Answer 2

Answer:

800 could not be the price that Karthi paid for one book.

Step-by-step explanation:

Given that :

• Karthi brought 5 books
• Average price paid for one book = Rs. 150.

Solution :

• Karthi brought 5 books and average price paid for each book is Rs. 150.
• Total price paid by Karthi for 5 books is = 5 x 150 = Rs. 750
• Since, Karthi paid a total of Rs. 750 for 5 books.
• So, price of any one can not be equal to or greater than 750.
• In other words, price of each book must be less than Rs. 750.
• Hence, Karthi could not have been paid Rs. 800 for one book.
