Determining which percentage of a sample belongs to a sample set

First and foremost, I'm a programmer and statistics is NOT my forte so
I hope I'm posting to the right place. I'm looking for direction in
regards to the following scenario:

- I have sample data made up of components in which each component is a
pecentage of the whole sample. For instance component1 represents 10%,
component2 represents 40%, etc.

- I have 2 samples from which I want to use as comparison/reference
points

- I have a 3rd sample that's a combination of samples 1 and 2 and I
KNOW the component percentages of the 3rd sample but I don't know which
percentage came from sample1 and which percentage came from sample2.

I need to determine with some degree of accuracy as to which percent
(as a whole) is made up of sample1 and which percent (again as a whole)
is made up of sample2 by comparing the component percentages of sample3
to those of samples 1 and 2.

Can anybody help me out with this? A formula would be great!!

Thank you!!!!
