Letting the Marbles Into the Bag
T4 wants to put his 231 marbles in bags. However, he decides to put them in such a way that he uses the greatest number of bags possible, with at least one marble per bag, and no two bags containing the same number of marbles. What is the number of bags?
Hint
1) This might seem like math, but it's more like tricky logic.2) T4 put them in such a way that you cannot reach in and grab all of the marbles of the bag containing the most number of marbles.
3) The wordiness and technicalities in the body and the hint have a purpose.
Answer
231.At first you might think it's one in the first bag, two in the second bag... and you will have used all 231 marbles by the 21st bag. However, you can put one marble in each bag. Then, put the first bag into the second bag, so now the second bag really contains two marbles. The second hint refers to the fact that you will have to reach in 231 bags to get all the marbles of the bag containing the most number of marbles.

Thanks, great teaser but my brain actually worked this morning.
Couldn't he put it all in one bag because the teaser says he wants to put the marbles in a bag (a meaning one).
Well he wants the greatest number of marbles....
I meant bags used
I thought that no bag could contain the same number of marbles??
They don't... If a bag is inside another, the bag on the outside also conatins the marbles of the bags on the inside
You got me. Should have looked at the catagory. Nice one.
nice one, i did it the 21 way...
good teaser i thought it was easy though
Wow! That's Awesome!
Nice teaser.
i knew it was the 231 way. i pwn
Whoa to hard for me this morning!
Clever .
hahahahah good one!!!
Yeah, I agree this is one of the better ones.
Good Teaser. I guessed it, but i wasnt sure until I checked.
Yay. I don't know why, but the answer came to me very quickly. Excellent teaser!
Nice teaser. I would only mention though that there is another like this on this site.
Good teaser, although it was pretty confusing...
great trick and title to go along with it
very clever
I liked this one. It was pretty tricky, but I got it.
I don't understand why they had to put one bag into the other. If every bag has one marble, then no two bags have the same amount of marbles. Is that stretching it too much or isn't that what "trick" means?
NIce one, I like it!!
hmmm.... thi titla says : Letting the Marbles Into the Bag
so it means putting more than 1 marble into 1 bag.... hmmmm
so it means putting more than 1 marble into 1 bag.... hmmmm

sorry had to clear the mistakes on the first comment
weird teaser...i didnt get it
I got this one.
There was something like it in my math class last year, so it sounded familiar. But I did have to think about it for a few. I So think this Teaser was great, I got the answer but it wasn't easy.
Fantastic Job.

WELL DONE!
That's alot of bags...
that teaser made my brain hurt and seriously, why don't u take the easy way and not be so picky and put them all into ONE bag....
i agree
Very good. This is the first teaser I have given the max on being hard because it was very clever and well explained!
He could actually do it with 232. He can get one more bag and put no marbles in it at all.
Well, zero's an amount.
Well, zero's an amount.
i guessed 0 because it said possible
took me 5 seconds
