The sum of the number of digits in all the numbers between 31 and 400 inclusive is 1041.
I am not at all sure about "present". If you mean percent, the answer depends on which 100 numbers. Between 900 and 999, for example, the answer is 0%. For the FIRST 100 numbers: 1 to 100, the answer is 6%.
The answer to the smallest possible value of the sum of all the digits is 1. the number can either be 100 or 1000 - either way the sum is still one.
The sum is 1,060
5,050
The sum of all the digits of all the positive integers that are less than 100 is 4,950.

The sum of the number of digits in all the numbers between 31 and 400 inclusive is 1041.
The sum of all the the integers between 1 and 2008 (2 through 2,007) is 2,017,036.
I believe here are 51 such numbers.
