यदि \(A=\{1,2,3\}\) और \(R=\{(a,b):a<b\}\) है, तो कौन-सा pair (R) में नहीं होगा?
If \(A=\{1,2,3\}\) and \(R=\{(a,b):a<b\}\), which pair will not belong to (R)?
Explanation opens after your attempt
D. ( (3,1) )
Concept
The statement (3<1) is false, so \((3,1)\notin R\). Order is very important in an inequality relation.
Why this answer is correct
The correct answer is D. ( (3,1) ). The statement (3<1) is false, so \((3,1)\notin R\). Order is very important in an inequality relation.
Exam Tip
(3<1) असत्य है, इसलिए \((3,1)\notin R\)। inequality relation में order बहुत महत्वपूर्ण है।
