यदि \(A=\{2,3,6\}\) और \(B=\{1,2,3\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (y) संख्या (x) को विभाजित करती है?
If \(A=\{2,3,6\}\) and \(B=\{1,2,3\}\), how many pairs ((x,y)) in \(A\times B\) satisfy that (y) divides (x)?
Explanation opens after your attempt
Correct Answer
A. (7)
Concept
The valid pairs are ((2,1),(2,2),(3,1),(3,3),(6,1),(6,2),(6,3)). In divisibility, note which component is the divisor.
Why this answer is correct
The correct answer is A. (7). The valid pairs are ((2,1),(2,2),(3,1),(3,3),(6,1),(6,2),(6,3)). In divisibility, note which component is the divisor.
Exam Tip
सही युग्म ((2,1),(2,2),(3,1),(3,3),(6,1),(6,2),(6,3)) हैं। विभाज्यता में कौन सा घटक भाजक है यह ध्यान रखें।
