You should make all combinations of three numbers that give a product of 36. For instance: 1,3,12 and 1,6,6. When you do so, you will notice there are two combinations that add up to the same value- 13, all the other combinations give a different result when added up. So there are twins involved. So, if I didn't know how old they were by looking at the housenumber, that means the housenumber had to be 13 (1+6+6 or 2+2+9).

Otherwise, since the other combinations all add up to different numbers, I would have known their age by looking at the housenumber.
