Example 7: The relation a R b defined by a is factor of b on N is not (A) reflexive (B) transitive (c) anti symmetric (d) symmetric Ans. (d) Share with your friends Share 0 Neha Sethi answered this Dear student Reflexivity:For a∈N,a is a factor of a.Hence aRa ⇒ R is reflexive.Transitivity:For a,b,c∈N, a is a factor of b and b is a factor of c ⇒a is a factor of c.⇒R is transitive.Symmetry:For a,b ∈N a is a factor of b⇒b is a factor of a if a=b⇒ R is anti symmtric⇒R is not symmtric.Example : 2 is a factor of 4 but 4 is not a factor of 2.
