There is no number. 100 is the only one that has a hundreds digit. It's impossible.

440 or 541 or 642 or 743 or 844 or 945
194.There were actually two options, 194 and 083, but as it needs to be a three digit number, 194 is more fitting.
A zero
1We can not start a three digit number with 0, so 1 is the smallest digit.

The number is three hundred eighty-two. Therefore, the 3 is in the hundreds place.
I am a three digit number. all of my digit is multiples of 2. my hundreds digit is the lowest even number. the sum of my digits is 16. the units digit is the same as the difference between my hundreds and tens digits.
We have the relationship h = 1/3t, t = 1/3o, where h represents the hundred's digit, t represents the ten's digit, and o represents the unit's digit of the number. By substitution we get that h = 1/9o or o = 9h. The only possible solution among the digits {0, 1, 2, ..., 9} is o = h = 0 which leads to the number 000 which is not a three digit number, and o = 9, h = 1. It then follows that t = 1/3(9) = 3.Thus, the number is 139.
