Anita purchased a book from 'Satish Book Stores'. While reading the book she found that ten pages were missing. She approached the seller of the book and complained about the missing pages. The seller promised that if the publisher was ready to change the book he would change the same. After a week the seller informed Anita that the publisher had refused to change the book.
