Question

Let R = {(1, 3), (2, 2), (3, 2)} and S = {(2, 1), (3, 2), (2, 3)} be two relations on set A = {1, 2, 3}. Then RoS =

• A. {(1, 3), (2, 2), (3, 2), (2, 1), (2, 3)}
• B. {(3, 2), (1, 3)}
• C. {(2, 3), (3, 2), (2, 2)}
• D. {(2, 3), (3, 2)}

Answer 1

Answer: (C)

{(2, 3), (3, 2), (2, 2)}

Answer 2

Here $S = \{ ( 2,1 ) ; ( 3,2 ) ; ( 2,3 ) \}$

Then .
