(1+3=4) सम है, इसलिए ( (1,3) ) odd-sum relation में नहीं है। sum की parity जरूर जांचें। / Since (1+3=4) is even, ( (1,3) ) is not in the odd-sum relation. Always check the parity of the sum.
Mathematics Answer, Explanation and Revision Hints
यदि \(A=\{1,2,3\}\) और \(R={(a,b):a+b\) is odd(}) है, तो कौन-सा pair (R) में नहीं है? / If \(A=\{1,2,3\}\) and \(R={(a,b):a+b\) is odd(}), which pair is not in (R)?
Correct Answer: C. ( (1,3) ). Explanation: (1+3=4) सम है, इसलिए ( (1,3) ) odd-sum relation में नहीं है। sum की parity जरूर जांचें। / Since (1+3=4) is even, ( (1,3) ) is not in the odd-sum relation. Always check the parity of the sum.
