    Question Problem FIVE

    Problem 5

    TRIPOLLO

    TRIPOLLO is a strategy game in which numbered marbles are placed in a rectangular array of holes on a board. As shown, there are three rows of holes. A player wins if the marbles are placed so that in each column, the sum of the numbers in the first two rows is three times the number in the third row.

    (a) John has a 5-column board and marbles numbered 1 to 15.
    So far he has placed them as shown in the diagram.



    Show how he could successfully place the remaining marbles.

    (b) With the same board and marbles. John made the following start:



    Can he successfully complete this game? Give reasons.

    (c) You have an 8-column board and marbles numbered 1 to 24. Show how you can win by placing all the marbles on the board.

    (d) Show that with an 11-column board and marbles numbered 1 to 33 it is not possible to find a winning placement.

    Explain the problem in as much detail as you can.

    Hello Mr.Fantastic
    No, this is not a question from a maths competition. it's 1 of the 6 questions I picked out from the monthly issued maths challenge. My previous posts will explain the purpose of these 6 questions. It is to provide maths lovers some challenging questions to do. Please refer to my previous post for more information.

    Yes, I've seen that thread. I just find it odd that the same questions are being posted by other members too.

    It may very well be that this question/problem is quiet wide known and is used in different occasions, whoever posted the same problem as I have posted here, could be another occasion. And please, if you dont mind. We're taking too much space talking in here, it would be difficult for members to read the answer replies. If there is any questions or replies or issues you want to make please contact me through PM. As it is more easier that way.

    Thank You,
    Mr`Fantasy

    This question is NOT from the Australian Maths Challenge Competition. The member has posted it in good faith. Please feel free to reply.

    Apologies for any embarassment caused - I hope you understand that all members need to be vigilant for the sort of cheating that does sometimes occur.
