Most natural for whom?? For some people the most natural assumption
*is* that when one computes rates of return, it is the rate of return
on an
income *stream* and thus assumes that all monies received are re-
invested.
The solution to a problem should NOT depend on the level of domain
expertise of the
problem solver.

I disagree. With this interpretation questions are no longer just
about solving a
mathematical problem, but also about *guessing* what the poser of the
question
intended. This can be a cultural/psychological matter that has
nothing to do with
mathematics.

Mathematical questions should be posed in a clear concise manner that
does
*not* require interprtation of intent.

It would have been easy in the original question to state: "simple
annual interest".
Failure to do so is a reflection of the lack of competence of the one
who wrote the
problem.
