Well, isn't that just a happy little mystery we have here! Let's take a closer look at our clues. If the tens digit is half the hundreds digit and the sum of the digits is 9, we can see that the hundreds digit must be 6, the tens digit is 3, and the units digit is 0. So the missing number X is 630. Happy solving, my friend!
There are 9 pages that use a single digit (pages 1-9), leaving 495 digits - 9 pages × 1 digit/page = 486 digits There are 90 pages that use 2 digits (pages 10-99), leaving 486 digits - 90 pages × 2 digits/page = 306 digits There are 900 pages that use 3 digits (pages 100-999); this would be 2,700 digits, so the number of pages is somewhere in the hundreds. 306 digits ÷ 3 digits/page = 102 pages in the hundreds. → total number of pages = 102 + 90 + 9 = 201 pages.
I think the answer is 612!1 (tens digit) which is odd is half of 2 (hundreds digit) and the sum is (6+1+2=9).

The answer depends on which number is missing. It could be any number from 71 to 100.

Normally, at least three, but I can do it with two digits:27
A toll free phone number that is missing two digits
It is: 3 which represents 300
82
If the number formed by the last three digits is divisible by 8. This requires that: if the digit in the hundreds place is even, the last two digits must form a number divisible by 8 and if the digit in the hundreds place is odd, the last two digits must form a number divisible by 4 but not by 8.
