यदि \(A=\{1,2,3,4\}\) और \(R=\{(a,b):a\le b\}\) है, तो कौन-सा pair (R) में नहीं है?
If \(A=\{1,2,3,4\}\) and \(R=\{(a,b):a\le b\}\), which pair is not in (R)?
Explanation opens after your attempt
D. ( (4,2) )
Concept
The statement \(4\le2\) is false, so \((4,2)\notin R\). Watch the direction of the inequality carefully.
Why this answer is correct
The correct answer is D. ( (4,2) ). The statement \(4\le2\) is false, so \((4,2)\notin R\). Watch the direction of the inequality carefully.
Exam Tip
\(4\le2\) असत्य है, इसलिए \((4,2)\notin R\)। inequality में direction ध्यान से देखें।
