यदि \(R=\{(1,2),(2,1),(2,2)\}\) है, तो (R) के सममित होने के लिए कौन सा युग्म जरूरी नहीं है?

If \(R=\{(1,2),(2,1),(2,2)\}\), which pair is not required for (R) to be symmetric?

Explanation opens after your attempt
Correct Answer

D. ( (1,1) )

Step 1

Concept

For symmetry, the reverse of ( (1,2) ) is ( (2,1) ), and the reverse of ( (2,2) ) is itself. ( (1,1) ) is not necessary.

Step 2

Why this answer is correct

The correct answer is D. ( (1,1) ). For symmetry, the reverse of ( (1,2) ) is ( (2,1) ), and the reverse of ( (2,2) ) is itself. ( (1,1) ) is not necessary.

Step 3

Exam Tip

सममिति के लिए ( (1,2) ) का उल्टा ( (2,1) ) और ( (2,2) ) का उल्टा वही ( (2,2) ) चाहिए। ( (1,1) ) जरूरी नहीं है।
