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. |
