Title: Exercise your mind
Post by: Orior on August 20, 2007, 10:27:25 PM
Stop drooling over Rose of Tralee pictures with this...

Two men are talking.

Man A "Do you have any children?"

Man B "Yes, 3"

Man A "What age are they?"

Man B "The product of ages is 36"

Man A "Hmmm, I don't have enough info. Tell me more"

Man B "The sum of their ages is your house number"

Man A "Hmmm, I don't have enough info. Tell me more"

Man B "My eldest child is a vegetarian"

Man A "Ah, now I know"



What are the ages of the children?

Well, are we getting an answer?
Title: Re: Exercise your mind
Post by: Square Ball on August 21, 2007, 06:53:39 PM
i guessed 1,2 and 18, he said it was wrong, has to be correct as the product of these three numbers is 36, isnt it?
Title: Re: Exercise your mind
Post by: Hardy on August 21, 2007, 06:57:42 PM
But they're not the only three possible ages whose product is 36. But I went for that as well, for what I thought was a logical reason.
Title: Re: Exercise your mind
Post by: Square Ball on August 21, 2007, 07:02:05 PM
also then, 1,1, 36 or  2,2,9

Title: Re: Exercise your mind
Post by: Hardy on August 21, 2007, 07:09:32 PM
Or 1,3,12, or 1,4,9 or 1,6,6 or 2,3,6, or 3,3,4.
Title: Re: Exercise your mind
Post by: Square Ball on August 21, 2007, 07:11:15 PM
one of them have to be correct?
Title: Re: Exercise your mind

the standard answer to this puzzle is bollocks.  as the reason that is given isn't necessarily true. The phrase Irish twins may help you
Title: Re: Exercise your mind
Post by: Square Ball on August 21, 2007, 08:46:09 PM
are any of the above correct?

Title: Re: Exercise your mind
Post by: Hardy on August 21, 2007, 08:48:28 PM
I give up - heganboy or Orior, can you PM me the answer?
Title: Re: Exercise your mind
Post by: Square Ball on August 21, 2007, 08:49:53 PM
me too
Title: Re: Exercise your mind
Post by: Orior on August 21, 2007, 11:02:13 PM
Okay, I'll try to explain.

There are obviously several permutations to 36, i.e.

2, 2, 9
1, 6, 6
3, 3, 4
1, 2, 18
1, 1, 36
1, 4, 9

In the second step, we're told that the sum of the ages is his house number. 

2 + 2 + 9 = 13
1 + 6 + 6 = 13
3 + 3 + 4 = 10
1 + 2 + 18 = 21
1 + 1 + 36 = 38
1 + 4 + 9 = 14

There are two permutations that are the same. As the man did not have enough info after the second statement, then his house number must be 13

The third statment tells us that there is one eldest child (ie not twins).

So the childrens ages must be 2, 2 and 9

QED.

Makes sense to me.
Title: Re: Exercise your mind
Post by: heganboy on August 22, 2007, 02:46:21 AM
and its bollocks because:
you can have 2 6 year olds that aren't twins, i.e. born within a year of each other (irish twins)
Quod Erat isn't even close to Demonstrandum

heres one to think about.

was flicking the through the TV channels and came across the beginners guide to the cosmos, or something like that, they were talking about the size of the universe and all, and they stated that the universe is expanding, so my question is into what?

Oh and i have no idea

Over the past number of years my wifes arse is expanding and I have nightmares about the same question.

so

if the universe is expanding into the cosmos, is the cosmos expanding too?

Not necessarily, it exists already, but the extent of human knowledge isn't such that it (yet) knows the full reach of the boundaries of the cosmos (I think).
