“Get Those Thinking Caps On” 4

I hope those brains aren’t overworked because I have another challenge for you:

A book has 500 pages, numbered 1, 2, 3 and so on.

How many times does the digit 1 appear in the page number?

    But it also depends on how full the pages are Mr.Will. Is the last page also filled up?

    Well you were all on the right track but you only thought about how many times it would appear in the units place. What about in the tens or hundreds column?

    The answer actually is 200 times.

      I wasn’t sure if you ment only the units column or the whole number.
