The relation S on set {1,2,3,4,5} is S = {(1,1),(2,2),(3,3),(4,4),(5,5)} . The S is .........

The symmetric difference of A={1,2,3} and B={3,4,5} is {1,2}b{1,2,4,5} c.{4,3} d.{2,5,1,4,3}

If A={1, 2, 3, 4, 5} then the relation R={(1,1), (2, 2), (3, 3), (4, 4), (1, 2), (2,3)} is

If ={1.2.3.4,5,...,101,A={1,2,3,4,5}.A delta B={1,2,3,4), then n(B-A) is

Let the relation R on set A = {1,2,3,4,5} be defined as follows: R={(1,2),(2,1),(2,2),(3,3),(4,1),(2,4),(4,2),(1,5),(5,1),(5,5)} Then state which one is true in each of the following two cases

The symmetric difference of A={1,2,3}a n d\ B={3,4,5} is a. {1,2} b. {1,2,4,5} c. {4,3} d. {2,5,1,4,3}
