printing factory wants to pack a batch of books and send them to a bookstore (the same number of books is required for each pack). Workers were the first to receive this batch of books (11/18), and there were 40 books left after they were packed into 14 packs. Then they brought all the rest of the books. Together with the remaining books from the first time, exactly 10 packs were made. How many books are there in this batch?
