समुच्चय \(A=\{1,2,3\}\) पर relation \(R=\{(1,1),(2,2),(3,3),(1,2),(2,1),(2,3)\}\) है। (R) को सममित बनाने के लिए न्यूनतम कौन सा ordered pair जोड़ना होगा?
On \(A=\{1,2,3\}\), relation \(R=\{(1,1),(2,2),(3,3),(1,2),(2,1),(2,3)\}\) is given. Which minimum ordered pair must be added to make (R) symmetric?
Explanation opens after your attempt
Correct Answer
A. \((3,2)\)
Concept
For symmetry, ((3,2)) must accompany ((2,3)). The other required reverse pairs are already present.
Why this answer is correct
The correct answer is A. \((3,2)\). For symmetry, ((3,2)) must accompany ((2,3)). The other required reverse pairs are already present.
Exam Tip
सममित होने के लिए ((2,3)) के साथ ((3,2)) होना जरूरी है। बाकी आवश्यक उल्टे pairs पहले से मौजूद हैं।
