Episode 8: A Dragon & 2 Scientists

A dragon caught two scientists for dinner. It told them that they would be freed if they figure out the (integer) ages of its two children. The dragon then whispers the product of the two numbers to Dr. Jeal and the sum of them to Dr. KyJan . They are not allowed to tell these numbers to each other.

Dr. Jeal: I don't know.
Dr. KyJan: I don't know, either!
Dr. Jeal: Then, I know!
Dr.KyJan : Then I know, too!



How old are the dragon-kids?!
