Sharon and Karen

Question

BMAD    62
Two algebra students decide to save time on their homework by sharing the work equally. But after a while Karen has only done three-fifths of the problems that Sharon has left, which in turn is four-sevenths of the amount that Sharon has done. How much faster must Karen work than Sharon,if they care to finish simultaneously?

There are two interpretations of what the "which" (in turn) referred to...

so there is a separate answer out there that is equally plausible.
