A printer numbers the pages of a book starting with 1 and uses 3089 digits in all. How many pages does the book have?1. 10402. 10483. 10494. 1050

Answer» Correct Answer - Option 3 : 1049

Calculation:

⇒ The single-digit page (From 1 to 9) = 9 digit

⇒ Double digit page (From 10 to 99) = 2 × 90 = 180 digit

⇒ Three digit page (From 100 to 999) = 3 × 900 = 2700 digit

⇒ Total digit used = 9 + 180 + 2700 = 2889

⇒ The remaining digit = 3089 - 2889 = 200

⇒ The number of page with four digits = 200/4 = 50

⇒ The required number of total page = 999 + 50 = 1049

∴ The required result will be 1049.
