यदि \(A=\{2,4,6\}\) और \(B=\{2,4,6\}\) हैं, तो \(A\times B\) में समान घटक वाले कितने युग्म होंगे?

If \(A=\{2,4,6\}\) and \(B=\{2,4,6\}\), how many pairs in \(A\times B\) have equal components?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

The equal-component pairs are ((2,2),(4,4),(6,6)). Do not count all (9) pairs, count only the pairs satisfying the condition.

Step 2

Why this answer is correct

The correct answer is B. (3). The equal-component pairs are ((2,2),(4,4),(6,6)). Do not count all (9) pairs, count only the pairs satisfying the condition.

Step 3

Exam Tip

समान घटक वाले युग्म ((2,2),(4,4),(6,6)) हैं। पूरी संख्या (9) नहीं, केवल शर्त वाले युग्म गिनें।
