\(A=\{1,2,3,4\}\) पर \(R=\{(a,b):a\mid b\}\) है। कौन सा युग्म (R) में नहीं है?
On \(A=\{1,2,3,4\}\), \(R=\{(a,b):a\mid b\}\). Which pair is not in (R)?

Correct Answer
D. ((4,2))
Concept
Since \(4\nmid 2\), \((4,2)\notin R\). In divisibility relation, treat the first component as the divisor.
Why this answer is correct
The correct answer is D. ((4,2)). Since \(4\nmid 2\), \((4,2)\notin R\). In divisibility relation, treat the first component as the divisor.
Exam Tip
\(4\nmid 2\), इसलिए \((4,2)\notin R\) है। भाग संबंध में पहले घटक को भाजक मानें।
