\(A=\{1,2,3,4,5\}\) पर \(R=\{(a,b):a+b\le 6\}\) के बारे में सही कथन चुनिए।
For \(R=\{(a,b):a+b\le 6\}\) on \(A=\{1,2,3,4,5\}\), choose the correct statement.
Explanation opens after your attempt
Correct Answer
A. यह सममित हैIt is symmetric
Concept
Because if \(a+b\le 6\), then \(b+a\le 6\) also. But ((5,5)) is absent, so it is not reflexive.
Why this answer is correct
The correct answer is A. यह सममित है / It is symmetric. Because if \(a+b\le 6\), then \(b+a\le 6\) also. But ((5,5)) is absent, so it is not reflexive.
Exam Tip
क्योंकि \(a+b\le 6\) होने पर \(b+a\le 6\) भी होगा। पर ((5,5)) नहीं है इसलिए स्वसम नहीं।
