यदि \(A=\{1,2,3,4\}\) पर \(R={(a,b):a\) divides (b}) है, तो कौन सा ordered pair (R) में नहीं है?
If \(R={(a,b):a\) divides (b}) on \(A=\{1,2,3,4\}\), which ordered pair is not in (R)?

Correct Answer
C. ( (3,4) )
Concept
Since (3) does not divide (4), \((3,4) \notin R\). In exams, check the direction of divisibility carefully.
Why this answer is correct
The correct answer is C. ( (3,4) ). Since (3) does not divide (4), \((3,4) \notin R\). In exams, check the direction of divisibility carefully.
Exam Tip
क्योंकि (3) संख्या (4) को विभाजित नहीं करती, इसलिए \((3,4) \notin R\)। परीक्षा में विभाज्यता की दिशा ध्यान से देखें।
