The door number is an irrelevance - end of. Whoever constructed this riddle was an amateur.... LOL

Also the fact that twins can be the same age and yet simultaneously older/younger merely compounds the flaw in the riddle's construction. I like Logic problems and often take on complex ones from a book I was given in hospital - if I get time I'll post up one of them in the next week or so.

I've just been on to Mr Hawking......... His take on it is that like me, he thinks the door number is an irrelevance as we do not know what it is from the clues given. Furthermore, it is more likely that the teacher has three separate children rather than twins, but obviously you cannot rule that out. In his opinion, the most likely combination is three children who are aged 9, 4 and 1. However the clues do not rule out ages 12, 3 and 1 or 6, 6 and 1. The above answers assume that twins count as the same age... if you want to be pedantic and acknowledge twins are older/younger than each other - the ages of the children could also be any one of the following combinations...... 36, 1 and 1 So.... without knowing the door number there are at least 3 possible answers to this riddle or potentially 6 answers for a pedant. That teacher has set an impossible task.......

The question has been answered. You're only debating with yourself.

It hasn't though Stuk. If the door number is 13 as you propose there are still 2 options? 6,6 and 1 and 9, 2 and 2. All I'm doing is pointing out how poorly constructed this riddle is considering it's a year 9 maths paper!

I think that year 9 children aren't going to argue that one twin is younger than the other one, or that it is possible to have two 2 year old children that are not twins, or that the teacher's multiple of 36 was actually in hexadecimal, as nobody said it wasn't.

Unfortunately you're pointing out that you don't get the answer, even after a few people have explained it.

Yes I get that the children have weighed up all the possibilities of combinations as I've outlined previously and can see the door number as 13 (probably) which leads them to deduce the 6, 6, 1 answer.... which is what was expected But as a fully paid up pedant So, rather than my responses pointing out that "I don't get the answer.... blah blah"... my responses show that I have given the problem a little more thought than others have. That's why I got an 'A' for Pure Maths at A level.

That's why I got an 'A' for Pure Maths at A level. No it doesn't. I gave it the same thoughts, but came to the correct conclusion. Namely that if they're the same age there isn't a "youngest". That just shows that qualifications don't mean much.
