उत्तर

Let us define a relation R in R as aRb if a ≥ b. Then R is reflexive, transitive but not symmetric.

Explanation:

Given  that, aRb if a ≥ b

⇒ aRa

⇒ a ≥ a which is true.

Let aRb, a ≥ b, then b ≥ a which i not true,

So R is not symmetric.

But aRb and bRc

⇒ a ≥ b and b ≥ c

⇒ a ≥ c

Hence, R is transitive.
