Which relation on (A={1,2,3}) is non-empty but not reflexive?कौन-सा संबंध (A={1,2,3}) पर न तो रिक्त है और न परावर्ती है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R={(1,2),(2,3)})(R={(1,2),(2,3)})
Step 1: The second relation is non-empty because it has pairs. Step 2: But it does not contain ((1,1),(2,2),(3,3)), so it is not reflexive. Step 3: Keep the difference between non-empty and reflexive clear.चरण 1: दूसरा संबंध खाली नहीं है क्योंकि उसमें युग्म हैं। चरण 2: लेकिन उसमें ((1,1),(2,2),(3,3)) नहीं हैं, इसलिए वह परावर्ती नहीं है। चरण 3: गैर-रिक्त और परावर्ती में अंतर साफ रखें।
