On (A={2,3,4}), (R={(2,2),(3,4),(4,4),(2,3)}). Which required pair is missing?(A={2,3,4}) पर (R={(2,2),(3,4),(4,4),(2,3)}) है। कौन सा आवश्यक युग्म अनुपस्थित है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((3,3))((3,3))
Step 1: The required self-pairs are ((2,2),(3,3),(4,4)). Step 2: ((3,3)) is not present in the given (R). Step 3: In a reflexive relation, every element must be connected to itself.चरण 1: (A) के जरूरी अपने-अपने युग्म ((2,2),(3,3),(4,4)) हैं। चरण 2: दिए गए (R) में ((3,3)) नहीं है। चरण 3: परावर्ती संबंध में हर तत्व को खुद से जोड़ना न भूलें।
