यदि \(A=\{1,2,3\}\) और \(R=\{(a,b):a>b\}\) है, तो कौन-सा pair (R) में नहीं है?

If \(A=\{1,2,3\}\) and \(R=\{(a,b):a>b\}\), which pair is not in (R)?

Explanation opens after your attempt
Correct Answer

D. ( (1,3) )

Step 1

Concept

The statement (1>3) is false, so \((1,3)\notin R\). Do not change the order in an inequality relation.

Step 2

Why this answer is correct

The correct answer is D. ( (1,3) ). The statement (1>3) is false, so \((1,3)\notin R\). Do not change the order in an inequality relation.

Step 3

Exam Tip

(1>3) असत्य है, इसलिए \((1,3)\notin R\)। inequality relation में ordered pair का क्रम न बदलें।
