You sure you got that riddle right? The only valid piece of information is that the sum of his three girls' ages is 72. That's three variables, one equation -- unsolvable.

 

Twins who are 23 1/2 and one who is 25


EDITED AGAIN: Extremist was responding to a less valid answer of mine. Just meant as a temporary joke.

EDITED AGAIN AGAIN: Just so That I dont put Extremist in a bad light I'll post my first suggestion: The oldest daughter is 72. then the father adopted two twins at the age of 0. So the eldest is the only one who "likes" anything.

Now Nobleman, if daughter is 72, then how old is her father?

100?

[EDIT]

That was not nice Nobleman, now I look like idiot with reply. Bah!

Puzzle is not good. If I understood it right here it is.

--------------------------------------------------------

Their age sum up with house number:

Youngest daughter's age = X
House number = Y

Ages:
youngest: X
middle: X+Y
eldest: X+Y+Y

72 = X+X+Y+X+Y+Y = 3X + 3Y
or
24 = X + Y

It is obvious from here that middle daughter is 24.

Now, only what is left is to determine Y.

--------------------------------------------------------

Since he nowhere mentions house number - I guess Y should be determined from "the eldest likes chocolate ice cream".
I bet that this is his private joke here and only him knows the answer.

Huh? How in the world did you get that math?

Say the three daughters are X, Y, and Z.

From his post, X+Y+Z=72.

The next clue is that the their ages add up to the house number. Call that H. So:

X+Y+Z=H.

So the only thing determinable from this riddle is that the house number is 72.

 

He is absolutely right Capstone. Its just how to interpret the sentence: their ages add up to the house number

So they are 23 24 25
or they are 22 24 26
or they are 20 24 28

The Icecream part might shed some light on this. but I fail to see.

But Perhaps the sentence their ages add up to the house number might be understood otherwise

Hehe. The product is 72, not the sum.
Their ages are 8, 3 and 3.

 

Bah! In that case you could get these possibilities:
2, 2 and 18
2, 3 and 12
2, 4 and 9
2, 6 and 6
3, 3 and 8
3, 4 and 6

But none of these DON'T sum up in any rule. Or I'm blind?

[EDIT]

I haven't put combos with age 1 on purpose.

[This message has been edited by Extremist (edited September 16, 2001).]

 

The man knows the number of the house and says that it's not enough. That means that it has to be one of the two possibilities that give the same sum. These are 6, 6 and 2, and 8, 3 and 3. Now since he says his eldest daughter likes chocolate ice cream, it has to be 8, 3 and 3, as he otherwise would have two equally old daughters.

 

Azardu you are telling me that the original post has a typo? what is this madness.

 

You forgot this Azardu:

[EDIT]

I suggest that we leave this thread to rot unless kemanmaldea comes and clears his typos. Ok?

[This message has been edited by Extremist (edited September 16, 2001).]

 

Azardu got it right:
if you find all the three number combinations that equal 72 when multiplied you find out that 2 sets have the same number when added; 14.
this gives you two posible answers to their ages but the last piece says that the eldest ONE likes chocolate ice cream (note the one) one of the sets had two doughters of the same age.. so that one is out leaving you with 8,3,3

 

Excuse me? 14? Where did you suck out THAT 14 now?

 

Extremist:
You visit your neighbor's house and discover that he has 3 daughters when you inquire about their ages you get the falloing riddle
Their ages when multiplied togeter equal 72;
that means:
2, 2 and 18
2, 3 and 12
2, 4 and 9
2, 6 and 6
3, 3 and 8
3, 4 and 6
you tell him that that isn't enough information and get;
their ages add up to the house number;
still not enough information you tell him;
that means:
2, 6 and 6
3, 3 and 8
cos any other combination and you WOULD HAVE ENOUGH INFORMATION. you didnt, cos these two both add up to the same number, 14.
the eldest likes chocolate ice cream.
that means:
3, 3 and 8
cos only one eldest.

geddit?

 

Doh!

Ok, geddit. The point is YOU KNOW THE HOUSE NUMBER - and you need one info more because two answers can be true. It was not matter if it was 14 or any else number...

However, I DO ASSURE YOU that I don't know house numbers of my neighbors. So not mentioning in original puzzle that you KNOW neighbor's house number is not so clear. At least to me.

Whatever, you won.

umm people i hate to say this but:

They do not give you the house number so any three multiples of 72 will do!

Dargorn I suggest you to remove that post

Not only did Azardu solve the riddle he did it by finding the Typo in the text very impressive. indeed

[This message has been edited by Nobleman (edited September 16, 2001).]

 

I've solved the riddle once before, so I knew right away that it was a typo.

 

Cheater!

 

hehe

ok here's a new one if you don't mind. I think this is cool. And solvable =)

A king's royal court wizard has died and he needs a new wizard. There are three mages he can choose from so he decides to make some sort of a contest to determine the wittiest (lol is this a correct word ?) of the three.

Here's the puzzle:

the king has 5 wizard hats. 2 of them black, 3 of them WHITE (edited here). He binds the eyes of the mages and hides the 2 black hats and puts the remaining 3 white hats on each of the mages' heads.

He unfolds their eyes and tells them: The first who figures the color of the hat he/she is wearing will be the new royal wizard. If, however you make a guess and do not get the color right, you will be put to death summarily.

Each mage, of course, can see the colors of the other mages' hats but can not see his hat. After about half an hour or so, one of the mages screams in joy: mine is white !! And he is right.

How did he know (for sure)
