Why? It's the only one that has another option for the door number that fits the rest of the criteria. 9 2 & 2 doesn't leave a "youngest"

And the first prize of general brainbox goes to Stuk, double points if you get the second question (no cheating now)

Why can't it be 3, 3 and 4? The youngest child could still be Amanda - born last of the twins?
