The product of 3 brothers' ages is 567. Two are twins.
How old is the other one?
(In reply to
Here is my solution by Dan)
Not so fast, Einstein. 81 (3x3x3x3) is a square number that divides into 567 also !! So A=9 and B=7 is also a solution. The twins could be 9 and the other one 7. This solution would not require the virility of a Picasso.
