Combination of Assessment for a final score

Hi,

I need help with the following query that I have.


Problem Background:
A student is appearing for an exam. He has to appear for 5 (A, B, C, D & E) subjects. The 5 subjects have a different weightage totalling up to 100%. An examiner can assess the student on these subject on a rating scale of 0-100% (in multiples of 10 only).

Problem Statement:
I need to find out how many different ways are there to assess a student from 0% to 100% & what are those.
For example (please refer the attachment), there is only one way to assess the student at 100% which is assessing him at 100% in all the 5 subjects. Similarly there is only one way in which he can assess the student at 99% i.e. giving 100% in first 4 subject & giving 90% in the last subject. For 98% there are 2 options, 100% for 1st 4 subject & 80% for the last one or 90% for subject C & 100% for the rest. For 97% there can be 3 combination....

Any help that anyone can offer in finding out the assessment combination for each % point in excel 2007 would be highly appreciated.

Thanks,
Vinod
