MCQ

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:

✓
{(3, 3), (3, 1), (5, 2)}
B
{(1, 3), (2, 5), (3, 3)}
C
{(1, 3), (5, 2)}
D
none of these.

✓

Answer

Correct option: A.

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

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

Solution:
$A=\{1,2,3\}, B=\{1,3,5\}$
$R=\{(1,3),(2,5),(3,3)\}$
$\therefore R^{-1}=\{(3,3),(3,1),(5,2)\}$
