यदि \(R=\{(1,2),(2,4),(3,1)\}\), तो \(R^{-1}\) क्या होगा?
If \(R=\{(1,2),(2,4),(3,1)\}\), what is \(R^{-1}\)?
Explanation opens after your attempt
Correct Answer
A. ({(2,1),(4,2),(1,3)})
Concept
In the inverse relation, the positions in each ordered pair are interchanged. Thus ((1,2),(2,4),(3,1)) become ((2,1),(4,2),(1,3)).
Why this answer is correct
The correct answer is A. ({(2,1),(4,2),(1,3)}). In the inverse relation, the positions in each ordered pair are interchanged. Thus ((1,2),(2,4),(3,1)) become ((2,1),(4,2),(1,3)).
Exam Tip
व्युत्क्रम संबंध में हर क्रमित युग्म के स्थान बदलते हैं। इसलिए ((1,2),(2,4),(3,1)) से ((2,1),(4,2),(1,3)) मिलते हैं।
