Find two numbers that are odd and divide exactly by both 5 and 3?

Since it is odd, the number must end in 5 (since 5 requires it end in 0 or 5 and 10's are evens) and the digits must add up to a multiple or 3 for it to be divisible, looking at the series of real numbers ending in a 5:
5, 15, 25, 35, 45, 55, 65, 75 ...
15 (1+5=6) is the obvious choice since it's 3*5, then every 3rd number in the series (add 30, a multiple of 3) so 45, 75, 105, 135, 165, etc. would be solutions.
