A boy was playing with a book and tore out the pages 7, 8, 100, 101, 222 and 223. How many pages did he tear out?

Question

There are 2 books sitting side by side, consisting of exactly 100 pages.
The book on the left is upside down.
If you add the page number at the extreme left side of the book on the left to the page number at the extreme right side of the right hand side book, what is the total?
