यदि \(A=\{1,2,3\}\) और \(R=\{(1,1),(2,2),(3,3),(1,3),(3,1)\}\) हो तो (R) का विलोम क्या होगा?
If \(A=\{1,2,3\}\) and \(R=\{(1,1),(2,2),(3,3),(1,3),(3,1)\}\), what is the inverse of (R)?
Explanation opens after your attempt
Correct Answer
A. (R) ही(R) itself
Concept
The reverse of every pair is already present in (R). Therefore \(R^{-1}=R\).
Why this answer is correct
The correct answer is A. (R) ही / (R) itself. The reverse of every pair is already present in (R). Therefore \(R^{-1}=R\).
Exam Tip
हर युग्म का उल्टा युग्म पहले से (R) में मौजूद है। इसलिए \(R^{-1}=R\) है।
