If (A={0,1,2}) and (R={(a,b):ab>0}), how many pairs must be added to make (R) reflexive?यदि (A={0,1,2}) और (R={(a,b):ab>0}) है, तो (R) को प्रतिवर्ती बनाने के लिए कितने युग्म जोड़ने होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 11
Step 1: On the diagonal, (ab=a^2). Step 2: For (a=1,2), (a^2>0) is true, but for (a=0), (0>0) is false. Step 3: Only ((0,0)) must be added.चरण 1: विकर्ण पर (ab=a^2) होगा। चरण 2: (a=1,2) पर (a^2>0) सत्य है, पर (a=0) पर (0>0) असत्य है। चरण 3: केवल ((0,0)) जोड़ना होगा।
