Class 11 Mathematics Relations and Functions Relations Easy Level 27

यदि \(A=\{1,2,3\}\) और \(R=\{(a,b):ab=6\}\) है, तो कौन-सा pair (R) में है?

If \(A=\{1,2,3\}\) and \(R=\{(a,b):ab=6\}\), which pair is in (R)?

Explanation opens after your attempt
Correct Answer

B. ( (2,3) )

Step 1

Concept

Since \(2\cdot3=6\), ( (2,3) ) belongs to the relation. In a product condition, check the product of both components.

Step 2

Why this answer is correct

The correct answer is B. ( (2,3) ). Since \(2\cdot3=6\), ( (2,3) ) belongs to the relation. In a product condition, check the product of both components.

Step 3

Exam Tip

\(2\cdot3=6\), इसलिए ( (2,3) ) relation में है। product condition में दोनों घटकों का गुणनफल देखें।
