Bob and mark talk about their families. bob says he has 3 kids, the product of their age is 72. he gives another clue: the sum of the ages of his children. mark points out there is still not enough information to accurately guess. finally, bob says, my youngest child called justice . mark can then correctly determine the ages of bobs children . what are the ages ?

Possible Ages      Sum of The Ages 1  2  36                      391  4  18                      231  8  9                        181  3  24                      282  3  12                      172  4  9                        152  6  6                        142  2  18                      223  3  8                        143  4  6                        13

The sum has to be 14. So it can be 2, 6, and 6 or 3, 3, and 8.
But it cannot be 3, 3, and 8 because the youngest cannot be a twin.

So it is 2, 6, and 6.

Hope this helps :)
