यदि \(A=\{1,2,3,4,5\}\) और \(R=\{(a,b):|a-b|\leq 2\}\) हो तो कौन सा युग्म (R) में है?
If \(A=\{1,2,3,4,5\}\) and \(R=\{(a,b):|a-b|\leq 2\}\), which pair is in (R)?
Explanation opens after your attempt
C. \((3,5)\)
Concept
Since (|3-5|=2) and \(2\leq 2\), \((3,5)\in R\). In absolute difference, equality with the bound is included.
Why this answer is correct
The correct answer is C. \((3,5)\). Since (|3-5|=2) and \(2\leq 2\), \((3,5)\in R\). In absolute difference, equality with the bound is included.
Exam Tip
(|3-5|=2) और \(2\leq 2\) है इसलिए \((3,5)\in R\) है। निरपेक्ष अंतर में सीमा बराबर होने पर भी युग्म शामिल होता है।
