Let A = [1, 2, 3], B = [1, 3, 5].
Question:

Let A = [1, 2, 3], B = [1, 3, 5]. If relation R from A to B is given by = {(1, 3), (2, 5), (3, 3)}, Then R−1 is

(a) {(3, 3), (3, 1), (5, 2)}

(b) {(1, 3), (2, 5), (3, 3)}

(c) {(1, 3), (5, 2)}

(d) None of these

Solution:

 (a) {(3, 3), (3, 1), (5, 2)}

A = {1, 2, 3}, B ={1, 3, 5}

R = {(1, 3), (2, 5), (3, 3)}

∴ R−1 = {(3,1),(5,2),(3,3)}
