Question

The Number of Pages of a book Require 1152 digits while writing then how many total number of pages are in the book​

Answer 1

Answer:

492 digits are required.

If your book has no preface pages and foreword pages numbered by Roman numerals,then the answer is 492.

To number 200 pages we need numbers 1-200 which includes 9 one digit numbers(1-9),90 two digit numbers(10-99) and 101 (100-200)three digit numbers.

The number of digits required to number pages 1-9: 1*9 = 9 since they are all one digit numbers.

The number of digits required to number pages 10-99 : 90*2 (since they all are two digit numbers)= 180

The number of digits required to number pages 100-200 : 101*3(since they all are 3 digit numbers)= 303

Total number of digits required to number all the 200 pages: 303+180+9=492
