How old are your kids?

[AxyGaming]

Two men (Jim and Tim) have not seen each other in many years.


After talking for some time the following dialog occurs:

Jim: Are you married?
Tim: Yes

Jim: Have any kids?
Tim: Yes, three

Jim: How old are they?
Tim: You tell me!

Jim: I can't!
Tim: The product of their ages is 36

Jim: I still can't!
Tim: See the building across the street, count the windows
(Jim counts them)

Jim: There are....
Tim: Right, the sum of their ages is the same number as the number of windows!

Jim: I still can't
Tim: My youngest has red hair

Jim: I know their ages, they are...
Tim: Right you are!

How did Jim know???

Its fine! In the near future tho if you post anymore stories that’s where they go(:

I think it's in the right spot, as is! It's fun, and a logic puzzle!

Well, I've thought about this one, and don't see how it can be solved.

You can make two equations in three unknowns. But even there, in the 2nd equation, we are never told how many windows there are. Even if you assume floors have equal numbers of windows (which does not need to be necessarily true, although it often is), it still doesn't give you an answer.

And you can't rule out that there are twins or triplets.

If someone can solve this, I'd be surprised!

After counting the windows, Jim still didn't know the ages. This eliminates several possible age combinations, because their sums would be unique. Two combinations of ages however, have the same sum:1,6,and 6 equals 13; and 2,2, and 9 equals 13. Once Jim learns that one child is the youngest (i.e. not a twin), he knows that the ages are 1, 6, and 6.


Congrats to me lol

Nice one. You have any more?

This explanation sets off that 'perfectionist' disease in me. (lol)

If you look at the front on an apartment building, there will not be the same # of windows on every floor, and you will also have to ask yourself if the door, having a pane of glass would count, and, if it was a pair of swinging doors, would that count as two.

So in my mind, I just stopped trying to solve it, because you're just assuming too many things!
