How old could they be? The ages of a father and son add up to 66. The father's age is the son's age reversed.

From the statement above, I believe there are 3 possible solutions to the problem. The first is 15, 51 This means the son age can be 15 and the father 51 The second possible solution 24, 42 The son can be 24 years old and the father 42 The third possible answer is 06, 60 The son can be 06 years old and the father 60 years old. Another possible solution that can come to mind is 33, 33 but both father and son cannot be exactly the same age. This is why this possibility is not considered.
