यदि \(A=\{2,3,4,5\}\) और \(R=\{(a,b):a\ge b\}\) है, तो कौन-सा pair (R) में है?
If \(A=\{2,3,4,5\}\) and \(R=\{(a,b):a\ge b\}\), which pair is in (R)?
Explanation opens after your attempt
C. ( (5,3) )
Concept
Since \(5\ge3\), \((5,3)\in R\). Put the first component on the left side of the inequality.
Why this answer is correct
The correct answer is C. ( (5,3) ). Since \(5\ge3\), \((5,3)\in R\). Put the first component on the left side of the inequality.
Exam Tip
क्योंकि \(5\ge3\), इसलिए \((5,3)\in R\) है। पहले घटक को inequality के बाएं भाग में रखें।
