    This is very similar to a question that I solved just here.

    Read carefully through what I wrote there, and try your problem using an identical method. If you can't get it to work, let us know, and we'll take it from there.

    Try using a Venn Diagram to map out the problem... you will need three overlapping circles one for French, one for Business and one for Music. Use the information given to fill in the appropriate spaces in the venn diagram. Using simple algebra you can determine the answers to all of your questions. Hope this helps.
