If `A = {1,2}, B = {1,2,3}` and `c = {1,2,3,4,5}` then the relation between A, B and C?

If A = {1, 2, 3, 4}, B = {3, 4, 5} and C = {1, 4, 5} then the value of A – (B nn C) is

If A = {1, 2, 3, 4}, B = {3, 4, 5} and C = {1, 4, 5} then the value of A - (B - C) is

If the arithmetic mean of 0, 5, 4, 3 is a , that of -1, 0, 1, 5, 4, 3 is b and that of 5, 4, 3 is c , then the relation between a , b and c is a=b=c (b) a : b : c=3:2:4 (c) 4a=5b=c (d) a+b+c=12

A= {1, 2, 3, 4, 5}, B= {1, 3, 5, 6}, C= {1, 2, 3} , then find the following sets. B- C

A= {1, 2, 3, 4, 5}, B= {1, 3, 5, 6}, C= {1, 2, 3} , then find the following sets. A- (B cap C)

If X= {1,2,3,....,10} and A={1,2,3,4,5} . Then, the number of subsets B of X such that A-B ={4} is a) 2^5 b) 2^4 c) 2^(5) -1 d)1

If A={1,2,3},B={3,4} and C={1,3,5}, find A xx(B uu C)

A= {1, 2, 3, 4, 5}, B= {1, 3, 5, 6}, C= {1, 2, 3} , then find the following sets. A - (B - C)

If A={1,2,3},B={2,3,4},C={3,4,5,6}, then prove that A-(B-C)={1,3}

If A=[[1,2],[3,4]] and B=[[2,3],[4,5]] , then find A+B-C=0 , then find C.
