Answer 1

The last page torn has the number :

This number has the digits 3,8, 5 in a different order from 385

We expect the last page to be :

853 given that this gives the maximum value when the order is reversed.

The number of pages is given by :

(Last page - first page) + 1

= (853 - 385) + 1 = 468 + 1 = 469

The answer = 469 pages.
