A, B, and C processed a total of 540 parts. It is known that A has processed (1/3) of the total number of parts, B has processed (1/4) the number of parts and C has half the number of processed parts minus 30. So how many parts did C process?
甲、乙、丙三人共加工了540个零件．已知甲加工了零件总个数的(1/3)，乙加工零件个数的(1/4)与丙加工零件个数的一半减去30个相等．那么丙加工了多少个零件？
