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
B. (3)
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.
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.
Exam Tip
समान घटक वाले युग्म ((2,2),(4,4),(6,6)) हैं। पूरी संख्या (9) नहीं, केवल शर्त वाले युग्म गिनें।
