You can put this solution on YOUR website! Anne is 8 years older than Carlos. Betty is 2 years younger that Carlos. The product of their ages is 60. How old is Anne.
----------
A = C + 8
B = C - 2
A*B*C = 60
============
A, B & C have to all be even, or all be odd.
They can't all be odd, as the product is even --> 3 even integers.
60 = 2*2*3*5
No integer solution.
