three cousins, allan,bob,and charlie,were sitting around watching football on tv. the game was really boring, so they started talking about how old they were. allan (the oldest)noticed that they were all between the ages 11 and 30. bob noticed that the sum of their ages was 70. charlie (the youngest) stated, "gee, if you write the square of each of our ages, all the digits from 1 to 9 will appear exactly once in the digits of the three squares. how old was each person?
