If (R={(1,2),(2,1),(2,3),(3,2),(1,1)}), which statement is correct?यदि (R={(1,2),(2,1),(2,3),(3,2),(1,1)}), तो कौन-सा कथन सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R) is symmetric(R) सममित है
Step 1: The reverse of ((1,2)) is ((2,1)). Step 2: The reverse of ((2,3)) is ((3,2)), and ((1,1)) is fine by itself. Step 3: When all reverse checks pass, the relation is symmetric.चरण 1: ((1,2)) का उलटा ((2,1)) है। चरण 2: ((2,3)) का उलटा ((3,2)) है और ((1,1)) अपने आप ठीक है। चरण 3: सभी युग्मों की उलटी जाँच पूरी होने पर सममितता मिलती है।
