The three dauthers ages

[Exploited]

Two old friends, mathematicians, met on the street. They was very happy, because they didn't see each other for a long time. They started talking:

- Hey George, how are you? How is your wife?
- I am very good old buddy... We have three dauthers!
- Oh really? How old are they?
- Haha you will not get away so easy with that one. If you multiply the three ages you will get 36 (A.B.C = 36). If you sum all of the ages you will get the number of that house over there (A+B+C=X)
editor note: Sadly you do not know the house number
- Hmmm... As far as I can see you are giving me totally incomplete information
editor note: really? He knows the house number and it is still incomplete?
- Oh yeah... I forgot to say - my oldest dauther is with blue eyes!
- Haha that's easy now - the ages are...

Now it's your turn guys - how old are the daughters?

Ok let's solve it step by step. Which numbers multiplied can make 36? Here are they:
1*1*36
1*2*18
1*3*12
1*4*5
1*6*6
2*2*9
2*3*6
3*3*4

Now let's see their sums:
1+1+36 = 38
1+2+18 = 21
1+3+12 = 16
1+4+5 = 14
1+6+6 = 13
2+2+9 = 13
2+3+6 = 11
3+3+4 = 10

We do not know the house number, but suddenly I am 100% sure that the house number is 13. That is because the other guy said "Hmmm... As far as I can see you are giving me totally incomplete information", which means that he have two or more equal numbers... well the only equals are 13

Now which one of those two? Now it's easy, because we know that the oldest daughter is with blue eyes - well we have twins in the first sum, which means that there is no oldest daughter...

Finally the answer is 2, 2 and 9 years

OMG,thats one of the best Phil.. Added karma
BTW,there is a small mistake.. Its 1*3*12=36 lol
