Hi - I've come into this one a bit late but I have read all the responses and I still am still unable to see anything in the question that suggests that the sum of the ages cannot be unique from the sum of any other possible combination of the ages. Can anyone out there please explain? My immediate thought was 2, 3 & 6 and I don't see why this, or any of the other combinations giving a product of 36, is not an acceptable solution.
sum of the 3 numbers can not be unique ... so to use your "solution" ... 2+3+6=11 ... you can not split 11 into other 3 numbers that would make a product of 36, can you?
so if I knew that we drank 11 beers and the product was 36, then I would know the ages ... however, I did not know the ages (because we did not drink 11 beers)
