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%.

### What is the percent of numbers whose digets add up to an odd number between one and one hundred?

Since we are talking for the sum of digits, then we are talking about 2-digit numbers between 1 and 100, which are 90 numbers (10 to 99). From these numbers only half of them satisfy the above condition, that is 45 numbers. So 50% of 2-digit numbers between 1 and 100 have an odd sum of their digits.
