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. Hate to point out the obvious, but twins can be and are actually older/younger - I know one set of twins born on different days... one just before midnight and one after. The oldest of them constantly bangs on about it. Unless they are born simultaneous by Caesarian section one will always be the younger. No... qualifications don't mean much... except that in my case I was able to retire at 50 financially secure and 11 years on still enjoying the lifestyle that those qualifications didn't do much for!

Depends on whether you believe that, if you asked a parent with two kids born in January and October the same year, and who are currently the same age (i.e. you ask in December) how old their youngest was, they would say "ten" (or whatever) or "I don't have a youngest because two are the same age". Personally, I'd expect to get the first of those responses. Given the nature of the phrasing of the question (i.e. "not enough information to reach an answer"

I've repeatedly put "youngest" as I know there are permutations where the children could be twins or the same age. You would both lose marks for saying there's information missing however. What you mean is there's not enough information to prove that, with what ifs and buts, you could come up with an alternate answer. The kid in the question can see the room number so it's not missing, you just need to work out what it is.

I totally get what you're saying, but the fact is that the statement "the youngest is called Amanda" is clearly in there to state "the youngest two children do not share the same age", and it just doesn't do that

there are 8 possible solutions to this: 1,1,36 If you take "youngest" to mean "youngest by 1 year or more" the solutions are: 1,2,18 note that 1,6,6 remains, as there is nothing to say there is a definite "oldest". But even if you take the question to read that every child has a "unique" integer age (ignoring months etc.) you have the possible solutions: 1,2,18 They all sum to different values, but then we don't know what the sum of their ages is. Or have I missed something?
