One of the maths class was trying to get some information from their teacher.
| Sally : | "How many chidren have you got, Mrs Smith?" |
| Mrs Smith: | "Three" |
| Sally: | "How old are they?" |
| Mrs Smith: | "If you multiply their ages together, it comes to 72" |
| Sally: | "That doesn't give us enough information, Mrs Smith" |
| Mrs Smith: | "If you add the ages you get the number of this room" |
| Sally: | "That still doesn't give us enough information, Mrs Smith" |
| Mrs Smith: | "The youngest is called Amanda" |
| Sally: | "Thank you. Now we know how old they are ! " |
Well, how old are they?
