Class 11 Mathematics Relations and Functions Relations Easy Level 26

यदि \(R=\{(1,2),(2,1),(3,3)\}\) है, तो (R) symmetric है या नहीं?

If \(R=\{(1,2),(2,1),(3,3)\}\), is (R) symmetric?

Explanation opens after your attempt
Correct Answer

A. हाँYes

Step 1

Concept

The pair ( (2,1) ) is present with ( (1,2) ), and ( (3,3) ) is its own reverse. Hence the relation is symmetric.

Step 2

Why this answer is correct

The correct answer is A. हाँ / Yes. The pair ( (2,1) ) is present with ( (1,2) ), and ( (3,3) ) is its own reverse. Hence the relation is symmetric.

Step 3

Exam Tip

( (1,2) ) के साथ ( (2,1) ) है और ( (3,3) ) अपना reverse खुद है। इसलिए relation symmetric है।
