12, 3, and 1 ???
R = 12 and E = 3 on the calculator?
Some combinations are eliminated by having a youngest dog (I presume it's suppose to be dog's?), being 433, 3611, 922.
661 and 922 both add to 13, so they're eliminated.
Nah, lost on it... and I'm thinking from the perspective of the second man :/
