यदि \(R=\{(1,1),(1,2),(2,2),(3,3)\}\) on \(A=\{1,2,3\}\), तो (R) परावर्ती है या नहीं?
If \(R=\{(1,1),(1,2),(2,2),(3,3)\}\) on \(A=\{1,2,3\}\), is (R) reflexive?
Explanation opens after your attempt
Correct Answer
A. हाँ, क्योंकि \((1,1),(2,2),(3,3)\in R\)Yes, because \((1,1),(2,2),(3,3)\in R\)
Concept
For reflexivity, all pairs ( (a,a) ) are required, and they are present here. The extra pair ( (1,2) ) does not break reflexivity.
Why this answer is correct
The correct answer is A. हाँ, क्योंकि \((1,1),(2,2),(3,3)\in R\) / Yes, because \((1,1),(2,2),(3,3)\in R\). For reflexivity, all pairs ( (a,a) ) are required, and they are present here. The extra pair ( (1,2) ) does not break reflexivity.
Exam Tip
परावर्ती होने के लिए सभी ( (a,a) ) युग्म चाहिए और यहाँ वे मौजूद हैं। अतिरिक्त ( (1,2) ) होने से परावर्तिता खराब नहीं होती।
