. What is the total number of digits printed, if a book containing 150
pages is to be numbered from 1 to
150?

Solution :-

Total number of pages in the book = 150

Total number of one digit numbers = From 1 to 9

= 1*9  

9 digits  

Total number of two digit numbers = From 10 to 99

= 2*90

= 180 digits

Total number of three digit numbers = From 100 to 150

= 3*51

= 153 digits

Total number of digits printed in the book containing 150 pages  

= Total number of one digit numbers + Total number of two digit numbers +

Total number of two digit numbers

= 9 + 180 + 153

= 342 Digits

Hence, total 342 digits are printed in the book which has 150 pages.
