यदि \(A=\{1,2,3,4,5\}\) और \(R=\{(a,b):a+b\le 6\}\) है, तो (R) के लिए सही कथन क्या है?
If \(A=\{1,2,3,4,5\}\) and \(R=\{(a,b):a+b\le 6\}\), what is correct for (R)?

Correct Answer
A. सममित लेकिन स्वतुल्य नहींSymmetric but not reflexive
Concept
Because (a+b=b+a), the relation is symmetric. But ((4,4)) is absent since \(8\le 6\) is false.
Why this answer is correct
The correct answer is A. सममित लेकिन स्वतुल्य नहीं / Symmetric but not reflexive. Because (a+b=b+a), the relation is symmetric. But ((4,4)) is absent since \(8\le 6\) is false.
Exam Tip
क्योंकि (a+b=b+a), संबंध सममित है। पर ((4,4)) नहीं है क्योंकि \(8\le 6\) असत्य है।
