\(A=\{1,2,3\}\) पर \(R=\{(1,1),(2,2),(3,3),(1,2)\}\) है। कौन सा property गलत है?
On \(A=\{1,2,3\}\), \(R=\{(1,1),(2,2),(3,3),(1,2)\}\). Which property is false?
Explanation opens after your attempt
Correct Answer
A. सममितSymmetric
Concept
\((1,2)\in R\) but \((2,1)\notin R\), so it is not symmetric. Since all diagonal pairs are present, it is reflexive.
Why this answer is correct
The correct answer is A. सममित / Symmetric. \((1,2)\in R\) but \((2,1)\notin R\), so it is not symmetric. Since all diagonal pairs are present, it is reflexive.
Exam Tip
\((1,2)\in R\) है पर \((2,1)\notin R\), इसलिए सममित नहीं है। Diagonal pairs होने से reflexive है।
