यदि \(A=\{1,4,7\}\) और \(B=\{2,5\}\) हैं, तो \(A\times B\) को निर्देशांक बिंदुओं की तरह दिखाने पर कितने बिंदु होंगे?
If \(A=\{1,4,7\}\) and \(B=\{2,5\}\), how many points are there when \(A\times B\) is shown as coordinate points?

Correct Answer
C. (6)
Concept
Each ordered pair can be treated as a point and there are \(3\times 2=6\) pairs. Use the same counting rule in coordinate questions.
Why this answer is correct
The correct answer is C. (6). Each ordered pair can be treated as a point and there are \(3\times 2=6\) pairs. Use the same counting rule in coordinate questions.
Exam Tip
हर क्रमित युग्म एक बिंदु जैसा माना जा सकता है और कुल \(3\times 2=6\) युग्म हैं। निर्देशांक प्रश्नों में भी वही गिनती नियम प्रयोग करें।
