Can anybody help me to solve this problem..

Just claculate in the numbering of how many pages:
is used only one digit -these are the pages from 1 to 9, i.e 9 pages
are used two digits - these are the pages from 10 to 99, multply their number with 2
are used three digits - these are from 100 to 366, multiply their number with 3

Then find the sum.
