यदि \(R=\{(1,2),(2,1),(1,1)\}\) समुच्चय \(A=\{1,2\}\) पर है, तो कौन सा युग्म जोड़ने पर (R) प्रतिवर्ती हो जाएगा?
If \(R=\{(1,2),(2,1),(1,1)\}\) is on \(A=\{1,2\}\), which pair should be added to make (R) reflexive?
Explanation opens after your attempt
Correct Answer
A. ((2,2))
Concept
To be reflexive, both ((1,1)) and ((2,2)) are needed. ((1,1)) is already present, so ((2,2)) must be added.
Why this answer is correct
The correct answer is A. ((2,2)). To be reflexive, both ((1,1)) and ((2,2)) are needed. ((1,1)) is already present, so ((2,2)) must be added.
Exam Tip
प्रतिवर्ती होने के लिए ((1,1)) और ((2,2)) दोनों चाहिए। ((1,1)) पहले से है, इसलिए ((2,2)) जोड़ना होगा।
