यदि \(R=\{(1,2),(2,1),(3,3)\}\), तो कौन सा युग्म \(R^{-1}\) में होगा?
If \(R=\{(1,2),(2,1),(3,3)\}\), which pair will be in \(R^{-1}\)?
Explanation opens after your attempt
Correct Answer
A. ( (2,1) )
Concept
Since \((1,2)\in R\), \((2,1)\in R^{-1}\). In the inverse, all ordered pairs are reversed.
Why this answer is correct
The correct answer is A. ( (2,1) ). Since \((1,2)\in R\), \((2,1)\in R^{-1}\). In the inverse, all ordered pairs are reversed.
Exam Tip
\((1,2)\in R\) होने से \((2,1)\in R^{-1}\)। व्युत्क्रम में सभी ordered pairs उलट जाते हैं।
