1. Determine whether each of the following relations are reflexive, symmetric and
(iii) Relation R in the set as
Any number is divisible by itself and .So it is reflexive.
but .Hence,it is not symmetric.
and 4 is divisible by 2 and 4 is divisible by 4.
Hence,it is transitive.
Hence,it is reflexive and transitive but not symmetric.
