2014 Camp selection solutions

Thanks to everyone who took part in the 2014 camp selection problems. We apologize for the delay in sorting out the invitations but … well, we just apologize. We hope to have the invitations out this week.

Please note that we do not provide detailed rankings of performances – either among those who are invited, or among those who are not. The problems are meant as selection problems only, so there are only two possible outcomes.

And, without further ado, here are some sample solutions (of course there are many variations and different techniques possible for all of these).

2014 Solutions

PS: Thanks to Ian for pointing out a couple of typos in the last two solutions (fixed now I hope).

You can leave a response, or trackback from your own site.

    Hi Michael

    Could you check the solutions of Q9 and Q10 please?
    While marking, we came across some errors in Q9 (regarding point D and quadrilateral ABXY) and Q10 (the answer seems to be 25^3 x 49)

    Thank you

    In question 3, there is another pair that satisfy the requirements. (3,3) ,

    I’m afraid (3,3) doesn’t work. It gives a perfect cube, but not the cube of a prime.

    easily. And because most online slots cost only a quarter to play, you can afford to spend hours and hours until

    Even though you could get a discount, investing in items you
    won’t utilize isn’t advised.
