Otherwise it's a question with 8 answers.

OK, I get it. Still 2 or more possible solutions following the second clue, meaning there must be 2 or more solutions, i.e. the sum must be 13.

so 1,6,6, or 2,2,9

so it must be 1,6,6, again assuming that 2,2,9 can't have a youngest. Which is bollocks, as I'm a twin and I'm younger by a minute. As my twin delights in reminding me.

Yes, that's been extensively covered.

Where is this pig problem?

 


Optimistic as ever

Sally: How many children have you got, Mrs Smith?
Mrs Smith: Three
Sally: How old are they?
Mrs Smith: If you multiply their ages together it comes to 36
Sally: That doesn’t give us enough information
Mrs Smith: If you add the ages, you get the number on the door over there
Sally: That still doesn’t give us enough information, Mrs Smith
Mrs Smith: The youngest is called Amanda
Sally: Thank you, now we know how old they are
How old are her children?


AND


Problem. — Place twenty-four pigs in four sties so that, as you go round and round you may always find the number in each sty nearer to ten than the number in the last.

So this is confusing me. You have 4 stys arranged around you and you circle them and every time you get nearer to 10? And it's not averages. I don't see how it could work.

If it was the final sty closer to 10, that is easy (and has many solutions). Any clue as to a factor I'm not considering?

Yeah, sorry, I'm being a bit slow today.

Pig problem - original post. And I just replied to it.

So here is my problem. I'll arrange the pigs as:

0,19,2,3

great, every pen I go to gets closer to 10, until I go round again. My final pen is 7 "off" the target value and the first goes back to being 10 off the target value and surely that will never change?

This isn't a mathematical problem I reckon.

As you've already said, it would not be possible.

This question was thought up by an Oxford professor of mathematics (clue)

Ah, so this is a maths problem, but an abstract one. I'll continue to wrack my brain. But in the meantime I need to get on with work

How would 3 be closer to 10 than 9?

Definitely not a numerical/maths only answer.

Maybe we all need to get stoned and reconvene later to discuss.
