यदि \(A=\{1,2,3,4,5\}\) और \(R=\{(a,b):a+b=6\}\), तो (R) किस गुण को संतुष्ट करता है?
If \(A=\{1,2,3,4,5\}\) and \(R=\{(a,b):a+b=6\}\), which property does (R) satisfy?
Explanation opens after your attempt
Correct Answer
A. सममितSymmetric
Concept
If (a+b=6), then (b+a=6), so the relation is symmetric. But all ((a,a)) are not present, so it is not reflexive.
Why this answer is correct
The correct answer is A. सममित / Symmetric. If (a+b=6), then (b+a=6), so the relation is symmetric. But all ((a,a)) are not present, so it is not reflexive.
Exam Tip
यदि (a+b=6), तो (b+a=6), इसलिए संबंध सममित है। लेकिन सभी ((a,a)) मौजूद नहीं हैं, इसलिए प्रतिवर्ती नहीं है।
