समुच्चय \(A=\{1,2,3\}\) पर \(R=\{(1,2),(2,3)\}\) है। symmetric closure में कौन से pairs जोड़े जाएंगे?
On \(A=\{1,2,3\}\), \(R=\{(1,2),(2,3)\}\). Which pairs will be added in the symmetric closure?
Explanation opens after your attempt
Correct Answer
A. ((2,1),(3,2))
Concept
In a symmetric closure, ((b,a)) is added for every ((a,b)). Thus ((2,1)) is needed for ((1,2)), and ((3,2)) for ((2,3)).
Why this answer is correct
The correct answer is A. ((2,1),(3,2)). In a symmetric closure, ((b,a)) is added for every ((a,b)). Thus ((2,1)) is needed for ((1,2)), and ((3,2)) for ((2,3)).
Exam Tip
Symmetric closure में हर ((a,b)) के साथ ((b,a)) जोड़ा जाता है। इसलिए ((1,2)) के लिए ((2,1)) और ((2,3)) के लिए ((3,2)) चाहिए।
