The biggest and baddest brain teaser I know I have posted like two times already in the past.
There are two men and two numbers A and B.
- Man 1 knows the product of these numbers (A*B)
- Man 2 knows the sum of both numbers (A+B)
- A and B are whole numbers (natural, what do you call it)
- A and B are >1 and their sum <100.
The following conversation develops.
- Man 1: I see the product of the numbers, but I don´t know the numbers A or B
- Man 2: I knew you´d say that
- Man 1: In that case, now I know the numbers
- Man 2: In that case, now I know the numbers too.
What are A and B?
