Question

Let A = {1, 2, 3, 4} and let R= {(2, 2), (3, 3), (4, 4), (1, 2)} be a relation on A. Then R is

• A. Reflexive
• B. Symmetric
• C. Transitive
• D. None of these

Answer 1

Answer: (C)

Transitive

Answer 2

Since (1, 1)$\notin R$so, is not reflexive.

Now (1, 2) $\notin R$, therefore R is not symmetric Clearly R is transitive.
