Question 1019457
We can assume leading 0's are allowed since we also want 1- and 2-digit numbers (e.g. 086 equals 86, and 002 = 2).


The hundreds digit can be 0,2,4,6 (4 choices), and the tens and units digit can be 0,2,4,6,8 (5 choices each). Multiplying, we get 4*5*5 = 100. However this includes 000 which isn't positive, so the total number of such integers is 99.
