Question

The total number of digits used in numbering the pages of a book having $366$ pages is

• A. $732$
• B. $990$
• C. $1098$
• D. $1305$

Answer 1

Answer: (B)

$990$

Given there are a total of $366$ pages.

Total number of digits = Number of digits in 1- digit page numbers + Number of digits in 2-digit page numbers + Number of digits in 3- digit page numbers

$=(1\times 9+2\times 90+3\times 267)=(9+180+801)=990$

Hence, option (B) is the correct answer.
