यदि \(A=\{1,2\}\) और \(B=\{2,5\}\) हैं, तो \(A\times B\) में सभी युग्मों के घटक-योगों का समुच्चय क्या है?
If \(A=\{1,2\}\) and \(B=\{2,5\}\), what is the set of sums of components of all pairs in \(A\times B\)?
Explanation opens after your attempt
A. ({3,4,6,7})
Concept
The sums are (1+2=3), (1+5=6), (2+2=4) and (2+5=7). Write each result once in a set.
Why this answer is correct
The correct answer is A. ({3,4,6,7}). The sums are (1+2=3), (1+5=6), (2+2=4) and (2+5=7). Write each result once in a set.
Exam Tip
योग (1+2=3), (1+5=6), (2+2=4) और (2+5=7) मिलते हैं। समुच्चय में परिणामों को एक बार लिखें।
