I have an answer but...
2 x 2 x 9 = 36; 2 + 2 + 9 = 13. Male twins each aged 2, whose teeth haven't yet devloped enough to enjoy hot dogs as the 9 year old does.
...is it the right one? Possible, but he didn't say that only his oldest son liked hot dogs so what you deduce wouldn't be sufficient proof. For all we know, more than one of his kids could like hot dogs.
