Take a look at the package answers.
http://www.ctan.org/tex-archive/macros/latex/contrib/answers/
I have used it quite a lot and it is a very useful package.
When I make the assignments, I type in the solution also so
that I can check the solutions easily when I am proof reading.
I then load the package with `nosolutionfiles' option.
\usepackage[nosolutionfiles]{answer}.
If I want the solutions in a separate file which I then input,
I load the package without this option:
\usepackage{answers}
Typically, I have both the lines in my file and comment out
whichever is not needed.
Best,
S. Venkataraman
