A printer, numbers the pages of a book starting with 1 and uses 1554 digits in all. How many pages does the book have ?
A455
B554
C612
D374
Answer:
B. 554
Read Explanation:
The single-digit page (From 1 to 9) = 9 digit
Double digit page (From 10 to 99) = 2 × 90 = 180 digit
Total digit used = 9 + 180 =189
The remaining digit = 1554-189=1365
The number of page with three digits = 1365/3=455
The required number of total page =99+455=554
