9 pages from 1 to 9 will require 9 digits;
90 pages from 10 to 99 will require 90*2=180 digits;
200-(90+9)=101 pages will require 101*3=303 digits.

Total: 9+180+303=492.

Answer: C.

The first part containing the unit digits is easy to understand, however the parts containing the tens digits and hundreds digits needs some extra clarification.

Each page from 1 to 9, inclusive (so total of 9 pages) needs one digit;
Each page from 10 to 99, inclusive (so total of 90 pages) needs two digits (for example page 12 needs two digits: 1 and 2);
Each page from 100 to 200, inclusive (so total of 101 pages) needs three digits (for example page 123 needs three digits: 1, 2 and 3).

Hope it's clear.

Thanks, the content question is not hard however it did not understand it because of the odd strange pronunciation! Thanks for the clarification!

After attempting hundreds of official GMAT questions (OG11.12 and 13) i can safely say that the language used by the GMAT will be less ambiguous and clearer..
