What’s the answer for that: A, B and C are 8 bit no’s. They are as follows:
A -> 1 1 0 0 0 1 0 1 B -> 0 0 1 1 0 0 1 1 C -> 0 0 1 1 1 0 1 0 ( – =minus, u=union)
Find ((A – C) u B) =? A.120 B. 130 C. 187 D.200

• A-C can be written as A+(-C).
  so,A-C=11000101 +(11000101)=10001010
  Now, (A-C)u B= 10001010 + 00110011 = 10111011
  
  In decimal it can be written as=187

• A-c=A+(-c)=11000101+(11000110)=10001011
  (A-C)+B=10001011+00110011=101111101
  (101111101)=190
