Options : 694792698784
Solution
To determine the number of digits used to number a book containing 300 pages, you need to consider the number of digits in each page number.
- Pages 1-9: These are single digit numbers, so there are 9 pages * 1 digit = 9 digits.
- Pages 10-99: These are double digit numbers, so there are 90 pages * 2 digits = 180 digits.
- Pages 100-300: These are triple digit numbers, so there are 201 pages * 3 digits = 603 digits.
Adding these together, the total number of digits used to number a book containing 300 pages is 9 + 180 + 603 = 792 digits. So, the correct option is 792.
