Question

If a relation R on the set {1, 2, 3} be defined by R = {(1, 2)},
then R is
(A) reflexive (B) transitive
(C) symmetric (D) none of these

Sachin Dravid · Answer

R is not reflexive as (1,1), (2,2) & (3,3) is not
belong to R
R is not symmetric as (1, 2) is belongs to R but (2,1)
is not belongs to R
It is clear from the relation R = {(1, 2)} that R is
not transitive

So , the answer is (D) none of
these

If a relation R on the set {1, 2, 3} be defined by R = {(1, 2)}, then R is (A) reflexive (B) transitive (C) symmetric (D) none of these
