I have a list of sub-totalled parts similar to this:
Part x Description 1 Used on Car 1
Part x Description 2 Used on Car 2
Part x Description 3 Used on Car 3
Part x Total 6
Part y Description 2 Used on Car 2
Part y Description 3 Used on Car 3
Part y Total 5
Part z Description 5 Used on Car 1
Part z Total 5
There are three different parts x, y and z which are used in differing
quantities on different models of cars.
I want to know:
a) how many parts are used only on car 1, only on car 2, etc.
b) how many parts are used on car 1 and car 2
c) how many parts are used on car 1, car 2 and car 3
etc.
for all of the various combinations.
Any ideas?
