63? But it has more than two one-digit factors.

We're not quite sure what the "2 digit numbers of 100" are.Do you mean all the "2-digit numbers you say as you count to 100" ?If that's it, then here's how to sum them:There are 100 of them, minus (1 through 9, and 100) = 100 - 10 numbers = 90 numbers.Make pairs of them . . .10 + 99 = 10911 + 98 = 10912 + 97 = 10913 + 96 = 10914 + 95 = 109..etc.There are 45 pairs, and every pair adds to 109.So the sum of all 90 numbers is (45 x 109) = 4,905.

The factors of 35 are 1, 5, 7, 35. All of them are odd. 7 and 35 are multiples of 7. 5 has a digit sum equal to 5. No number satisfies all of the conditions.

Seven of them.

The sum of all the integers between 100 and 999 is equal to 494450 - which also happens to be the answer to the sum 899 x 500 (which refers to the number of numbers multiplied by the mean number + 0.5).
