You did not state the problem correctly.  The problem as stated as twelve
different answers.  However, the following problem has exactly one answer:

The first asks "How old are they?", to which the second replies

	"The sum of their ages is thirteen, and the product of their
	ages is equal to your age."

The first says, "I can't tell their ages from that."
The second adds, "The oldest weighs 61 pounds."

The first says, "Now I know their ages."
