Your question was cut off. Here is an algebra formula for you.
30P + 30I = 60a a=all
35G = 60 - 8N 35G= 52 Germans, German and Irish and Polish, Polish and German
8N = people not German at all
52M-7A-13PG=32 German only
M=mixed n=not German at all
p=Polish I=Irish G=German only.
But since the question was cut off my work is only an example for you to use to work your assigned question. I would need to know what 10 represented to solve the problem.
