यदि \(A=\{1,2,3\}\) और \(R=\{(1,2),(2,3)\}\), तो \(R^{-1}\) क्या है?
If \(A=\{1,2,3\}\) and \(R=\{(1,2),(2,3)\}\), what is \(R^{-1}\)?
Explanation opens after your attempt
Correct Answer
A. ({(2,1),(3,2)})
Concept
In the inverse relation, the components of each ordered pair are reversed. Thus ((1,2)) gives ((2,1)) and ((2,3)) gives ((3,2)).
Why this answer is correct
The correct answer is A. ({(2,1),(3,2)}). In the inverse relation, the components of each ordered pair are reversed. Thus ((1,2)) gives ((2,1)) and ((2,3)) gives ((3,2)).
Exam Tip
व्युत्क्रम संबंध में हर ordered pair के घटक उलट जाते हैं। इसलिए ((1,2)) से ((2,1)) और ((2,3)) से ((3,2)) मिलेगा।
