Question

Let X be the set of all graduate in india

Answer 1

Step-by-step explanation:

xRy ⇒ x and y are graduates of the same university.

Reflexive xRx ⇔ x and y are graduates of the same university.

So, relation is reflexive.

Symmetric xRy ⇔ x and y are graduates of the same university.

implies, yRx ⇔ y and x are graduates of the same university.

So, relation is symmetric.

Transitive xRy, yRz ⇔ xRz

It means x and y, y and z are graduates of the same university, then x and z are also graduates of the same university.

So, relation is transitive.

Hence, relation is reflexive, symmetric and transitive
