If `R and R'` are symmetric relations (not disjoint) on a set A, then the relation `R uu R'` is (i) Reflexive (ii) Symmetric (iii) Transitive (iv) none of these

If R and R' are symmetric relations (not disjoint ) on a set A then the relation R cap R' is not

If R and R' are symmetric relations (not disjoint) on a set A ,then the relation R uu R' is (i) Reflexive (ii) Symmetric (ii) Transitive (iv) none of these

If R is a symmetric relation on a set A, then write a relation between R and R^(-1) .

If R is a symmetric relation on a set A , then write a relation between R and R^(-1) .

Let n be a fixed positive integer.Let a relation R be defined on Z, as aRb if n is divisible by a-b, then relation R is (i)Reflexive (ii)Symmetric (iii)Transitive (iv) all of these

On the set of natural number let R be the relation defined by aRb if 2a +3b=30. Write down the relation by listing all the pair . check whether it is (i) reflexive (ii) symmetric (iii) transitive (iv) equivalence

On the set of natural number let R be the relation defined by aRb if a+b lt=6 . Write down the relation by listing all the pairs. Check whether it is (i) reflexive (ii) symmetric (iii) transitive (iv) equivalence.

If R is an equivalence relation on a set A, then R^(-1) is A reflexive only B.symmetric but not transitive C.equivalence D.None of these
