Old STEP questions, struggling with solution

    Hey there!

    I'm struggling with the solution posted for math STEP II 2013 Q1. It is a fairly easy question, I understand the context and the solution, except for this one part.

    I won't be able to do the formatting well enough, so here is the link to the 2013 step paper:

    Also, here is the link to the solution posted on this forum:
    (I didn't want to revive this ageold thread)

    Specifically, what bugs me is the assumption in the solution that
    q / c > (gq + c) / (gp + c)

    With that assumption in this case, the whole question makes a lot of sense, but I seem to be unable to derive it.

    Sorry to keep referring to these ressources and not explaining the core of the problem myself - I just think that the question does a better job at that than I could do here.

    .I also hope this is not a doublepost, but I don't think it worked the first time I posted.

    ..Thanks so much!
