On (A={1,2,3}), (R={(1,1),(2,2),(3,3),(1,2)}) and (S={(1,1),(2,2),(3,3),(2,3)}). What is (R\cap S)?समुच्चय (A={1,2,3}) पर (R={(1,1),(2,2),(3,3),(1,2)}) और (S={(1,1),(2,2),(3,3),(2,3)}) हैं। (R\cap S) कैसा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Reflexiveपरावर्ती
Step 1: Both (R) and (S) contain ((1,1),(2,2),(3,3)). Step 2: These three pairs remain in the intersection. Step 3: Hence (R\cap S) is reflexive, even if extra pairs differ.चरण 1: (R) और (S) दोनों में ((1,1),(2,2),(3,3)) मौजूद हैं। चरण 2: प्रतिच्छेद में ये तीनों युग्म बने रहेंगे। चरण 3: इसलिए (R\cap S) परावर्ती है, भले ही अतिरिक्त युग्म अलग हों।
