If (R={(1,2),(2,1),(2,3)}), which pair should be added to make it symmetric?यदि (R={(1,2),(2,1),(2,3)}) है, तो सममित बनाने के लिए कौन-सा युग्म जोड़ना होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((3,2))((3,2))
Step 1: ((1,2)) and ((2,1)) already form a reverse pair. Step 2: The reverse of ((2,3)), which is ((3,2)), is missing. Step 3: To make a relation symmetric, add only the missing reverse pairs.चरण 1: ((1,2)) और ((2,1)) पहले से जोड़ी बनाते हैं। चरण 2: ((2,3)) का उलटा ((3,2)) गायब है। चरण 3: सममित बनाने में केवल गायब उलटे युग्म जोड़ें।
