    The new Lenny Cunundrum? I just can't figure it out. I'm trying to get the trophy.

    A certain Neopian is collecting piles of dung. (Trust me, I have no idea why)

    If you take the number of piles of dung they have, and divide them up into two unequal numbers, then 1545 times the difference between the two numbers equals three times the difference between the squares of the two numbers.

    How many piles of dung does the user have? Please enter only a single number; do not show your work or submit any other information.

    Any help is useful.

    1545(y-x) = 3(y^2-x^2)
    1545(y-x) = 3(y+x)(y-x)
    (3y+3x-1545)(y-x) = 0

    y =/= x soo....

    3y + 3x - 1545 = 0
    3(y+x) = 1545
    y+x = 515

    515 total

    Today's was a bit easier. The math ones tend to be rather easy. At least I have a chance of getting them by working it out, some are so hard that you can't really do it that way.
