1230 numeric chars to number book: how many pages?

[mel757]

it takes 1230 numeric characters (0's to 9's) to number the pages in a book. how many pages are there in the book?

would the answer be 447??

pages 1-9 = 9 characters
pages 10-00 be 190

1230- 189 = 1041 1041/3= 447?

Re: question

There are 9 characters form 1 to 9.

There are 180 characters from 10 to 99.

That leaves 1041 characters left or 347 numbers with 3 digits each.

347+180+9=536. It's a safe bet the pages are printed front and back, so 536/2=268 pages.

Unless I miscounted.
