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
Your Answer : (Not Answered) Correct Answer :
990
Explanation :
Total number of digits= No. of digits in 1- digit page nos.(1 to 9) + No. of digits in 2-digit page nos.(10 to 99) + No. of digits in 3- digit page nos(100 to 999).
First 9 pages having 1 digit nos (1x9=9 digits).
Next 90 pages having 2 digit nos (2 x 90=180 digits).
Remaining 267 pages having 3 digit nos (267x3 = 801 digits)
So total will be = (1 x 9 + 2 x 90 + 3 x 267) = (9 + 180 + 801) = 990.
