    Solution to Bonus Riddle: brilliant.org/...
    Townspeople are demanding that a corrupt merchant’s collection of 30 rubies be confiscated to reimburse the victims of his schemes. The king announces that the fine will be determined through a game of wits between the merchant and the king’s most clever advisor - you. Can you outfox the merchant and win back the greatest amount of rubies to help his victims? Dennis Shasha shows how.

    For the bonus riddle: 10
    The merchant will always take the 2 most valuable piles, only leaving you with the lowest value one. That means you can only get it if you split it into 3 equal piles, 10,10,10. If I take any out of any pile and put it in another the merchant will take that more valuable pile leaving me with one less than 10.

    • @guytanlol
      @guytanlol 4 роки тому +23

      Yes. The thing is that they say that the scoundrel CHOOSES and KEEP, so i guess he can see the piles... Btw, the first problem says that you want to guarantee the maximum number of rubies, but maybe other combinations could have a better risk/reward overall, i'm lazy about listing everything i should just do a computer program lol

    • @locksmack
      @locksmack 4 роки тому +80

      You are correct.
      However, if we assume that the scoundrel can't see the amount in each pile, then the answer is 28. This is because of the wording of the question - what is the MAXIMUM amount you can keep? If the two piles he choose each have just one ruby, then you can keep the pile with 28.
      Assuming 1 ruby can be called a 'pile'...

    • @Wishkeyn
      @Wishkeyn 4 роки тому +10

    For a second I thought the solution was wrong because in the merchant’s shoes, I’d have done 2-8-20, except that combo still gives you 16 gems by the proposed 8-8-8 method. And if you got lucky enough to hit the 8-8-14 scenario, that’s 24 gems for you. So good riddle, but perhaps the logic behind the solution could be explained better by showing more distribution patterns going through 8-8-8?

      If the 3 numbers are a b and c then
      A+6=B C=30-A-B
      A>1 B>1 C>1
      Resulting scenarios are:
      2 8 20
      3 8 18
      4 10 16
      5 11 14
      6 12 12
      7 13 10
      8 14 8
      9 15 6
      10 16 4
      11 17 2
      Choosing 8 8 8 (all of them have at least 2 numbers greater than 7) guarantees 16 rubies at least
      Best case would be 8 14 8, getting 24 rubies, any other case you get 16

    The way I solved it was thinking of 3 scenarios(using the same number on all 3 cards seems pretty straight forward):
    1. A box with minimum amount of rubies, so 2. The other two boxes bound by the +6 relation so 11 & 17. (2,11,17)
    2. A box with minimum amount of rubies, so 2. One other boxes bound to this one by the +6 relation so 8, and then 3rd box with what's left 14. (2,8,20).
    3. Starting with 11 in each box, satisfying the +6 relation while keeping rubies as evenly spread as possible: (8,8,14).
    While looking at these numbers in the last two cases, picking anything above 8 will yield just 1 box of stolen rubies with this number. In order for this to be better than 2x8 the number must be 17. But in the 3rd case this would give no rubies at all. Therefore picking 8 is the only logical solution.

      But since the difference must be exactly 6, the merchant now has very limited options. Whether it's (2,8,20), (3,9,18), (4,10,16), (5,11,14), (6,12,12), (7,13,10), (2,11,17), (6,9,15) or (8,8,14), if we write 8 on each paper we will get at least 16 rubies instead of only 8.

      There's nothing that says the scoundrel will choose the two largest piles, that is a (reasonable) assumption. But the question is what is the maximum number you "can" keep, which includes the possibility, however unlikely, that the scoundrel decides to take the two smallest piles. So technically, assuming that each pile has to have at least one ruby, the maximum number you "can" keep is 28.

  • @josephw3999

    From an expected value perspective, the answer would actually be 9. Even though there are two instances you would only get 9 rubies ( 8-8-14 or 20-2-8) this is actually outweighed by the fact that the other 8 times you are getting 18. This can be shown as 8*18 + 2*9 = 162 > 160 = 16*10. Note this answer is only true under the assumption that the merchant distributes his rubies at random. The riddle stated after the fact that the merchant would choose the worst case scenario.

    • @christianratuschny6533

    Its simpler to look at the graphs of

    At x=2, the intersection with the graphs are in
    2, 8, 12

    • @zat1245
      @zat1245 4 роки тому +2

      Interesting approach. This is why logic is fun, as long as you know the rules things can be approached in different ways but always seem to be closely related, just at a different angle. My solution was that the formula for the boxes were:
      a
      x
      x + 6
      since there are always 30 gems among them:
      a + x + (x + 6) = 30
      so
      a + 2x = 24 and I concluded that a has a range of even integers from [2, 20]. a can only be integers because there has to be an integer number of gems in the box that equals a. 2 is the smallest amount a can be because of the rules and 20 is the biggest because the smaller a is, the bigger x has to be so the inverse is true and the smallest x can be is 2 by the rules so in that smallest case, a = 20. a has to be even because the monomial 2x is even and so is 24. If one integer is even in a sum of two integers, the other has to be as well to produce an even number. So, I looked at the 10 cases made by the constraints and found that the two largest boxes are never lower than 8 in each case.

    There's a flaw in this riddle, the king never said that the merchant had to put all of the rubies in the collection of chests, he can at minimum put 12 up for grabs (2-8-2) and thus the answer isn't perfect (it is assuming he did put all 30 in the boxes)

      I think I got it!!. Supposing he can't see the piles (which is the only way all this makes any sense) you arrange the following piles of rubies: 15, 14 & 1. Thus you have a 66.7% chance of getting almost half the pile.

    Well, I knew from the beginning they were all going to be the same cards. I thought of three 10's, but realized it would be too easy to get stuck with just ten. I thought maybe of trying to find the highest number so I could get one successful batch at both 15 then 12. Then, I thought obviously if you put in for 6 or 8, you'd be sure to get two of them, so I settled with 8. I didn't have a proof, but I at least feel smart, lol. The one box being x + 6 was pretty confusing, but made 8 fairly obvious.

    Those appear to be the only ways the coins can be split. Of course we don't know which box is which. In each scenario, there is a minimum number of 2 boxes with 8 or more coins, so put 8 in front of each and you're guaranteed at least 16 coins. Best scenario is the last, where you get 24.

    The way this was worded, the second rule implied that there would be exactly one box that had exactly six more gems than exactly one other box. By that logic, 14 8 8, as well as 12 12 6 isn‘t possible, therefore I advised him to say nine on every single box. But I would have even understood if he would have guessed 10 because the expected value would still be 18 rubies, only 1/5 of the time he would get 10 rubies. But maybe I just understood it wrong

      The smallest possible numbers for exactly two boxes are 2 and 8, making 8 the only number that guarantees you get more than half the rubies no matter the arrangement. Everything else is risky.

  • @nathanwise1608
    @nathanwise1608 4 роки тому +4

    This one actually becomes pretty easy once you turn it into a math problem.
    As seen starting at 1:43, the normal amount of rubies in two of the boxes is x, and the number in one of the boxes is x +6.
    So, the problem can be written like this:
    3x + 6= 30
    3x=24
    x=8
    So, your best guess for each box is 8, just as the video concluded.

  • @LexxBM
    @LexxBM 6 місяців тому

    that was a fun riddle, but i figured out the solution in a different way:
    Minimum rubies per box: 2
    One of the boxes must have exactly six more than another: 2+6 = 8 that box must at least eight. Therefore, you should always guess 8.
    if the first box has 2, the second one has 8 and the third one has 20 (= 30 - 2 - 8)
    If you increase the rubies in box 1 by one, then the amount of rubies in box 2 also goes up by one, and the rubies in box 3 go down by two:
    2, 8, 20
    3, 9, 18,
    4, 10; 16
    5, 11, 14
    6, 12, 12
    7; 13: 10
    8, 14, 8
    Every configuration except for the last one yield 16 rubies 100% of the time. The last one gives a yield of 24, which is the highest you can get.
    The explanation in the vid is more elegant but i've always been bad at math and found this solution more intuitive :3
