यदि \(R=\{(a,1),(b,2),(c,3)\}\) है, तो \(R^{-1}\) में ((2,b)) के बारे में क्या सही है?
If \(R=\{(a,1),(b,2),(c,3)\}\), what is true about ((2,b)) in \(R^{-1}\)?
Explanation opens after your attempt
Correct Answer
A. \((2,b)\in R^{-1}\)
Concept
Since \((b,2)\in R\), reversing it gives \((2,b)\in R^{-1}\). Changing the order is the key point in inverse relations.
Why this answer is correct
The correct answer is A. \((2,b)\in R^{-1}\). Since \((b,2)\in R\), reversing it gives \((2,b)\in R^{-1}\). Changing the order is the key point in inverse relations.
Exam Tip
क्योंकि \((b,2)\in R\), इसलिए उलटकर \((2,b)\in R^{-1}\) होगा। प्रतिलोम में क्रम बदलना मुख्य बात है।
