यदि \(R=\{(1,2),(2,3),(1,3)\}\) और \(S=\{(2,1),(3,2),(3,1)\}\) हैं, तो (S) क्या है?
If \(R=\{(1,2),(2,3),(1,3)\}\) and \(S=\{(2,1),(3,2),(3,1)\}\), what is (S)?
Explanation opens after your attempt
A. \(R^{-1}\)
Concept
(S) contains the reverse of every pair in (R). Hence \(S=R^{-1}\).
Why this answer is correct
The correct answer is A. \(R^{-1}\). (S) contains the reverse of every pair in (R). Hence \(S=R^{-1}\).
Exam Tip
(S) में (R) के हर युग्म का उल्टा युग्म है। इसलिए \(S=R^{-1}\) है।
