Maths homework

You might not see it well, but it says Maths homework. I have one last sum. I am stuck on it! I have worked out an answer but you need more than one! If anyone knows the answer two- four children, none over 15 years. If you multiply their age the answer is 770.

The one who will comment the correct answer, will help me and obtain a free clubpenguin membership by e-mail! :)
