यदि \(A=\{1,2,3,4\}\) और \(R=\{(a,b):a+b\leq 5\}\) हो तो कौन सा युग्म (R) में नहीं है?
If \(A=\{1,2,3,4\}\) and \(R=\{(a,b):a+b\leq 5\}\), which pair is not in (R)?
Explanation opens after your attempt
D. \((4,4)\)
Concept
Since (4+4=8) and \(8\leq 5\) is false, \((4,4)\notin R\). For boundary conditions, also check equality.
Why this answer is correct
The correct answer is D. \((4,4)\). Since (4+4=8) and \(8\leq 5\) is false, \((4,4)\notin R\). For boundary conditions, also check equality.
Exam Tip
(4+4=8) और \(8\leq 5\) असत्य है इसलिए \((4,4)\notin R\)। सीमा वाली शर्त में बराबरी भी जांचें।
