(i) R is reflexive if it contains {(1,1),(2,2) and (3,3)}. Since, (2,2)∈R. So, we need to add (1,1) and (3,3) to make R reflexive.
(ii) R is symmetric if it contains {(2,2),(1,3),(3,1),(3,2), (2,3)}.
Since, {(2,2),(1,3),(3,2)}∈R. So, we need to add (3,1) and (2,3).
Thus, minimum ordered pairs which should be added in relation R to make it reflexive and symmetric are {(1,1),(3,3),(3,1),(2,3)}.
