यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,5,8\}\) और \(C=\{1,5,6,9\}\) हैं, तो (A\setminus\(B\cup C\)) क्या है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,5,8\}\), and \(C=\{1,5,6,9\}\), what is (A\setminus\(B\cup C\))?
Explanation opens after your attempt
A. ( {3,4} )
Concept
\(B\cup C={1,2,5,6,8,9}\). Removing (1,2,5,6) from (A) leaves (3,4).
Why this answer is correct
The correct answer is A. ( {3,4} ). \(B\cup C={1,2,5,6,8,9}\). Removing (1,2,5,6) from (A) leaves (3,4).
Exam Tip
\(B\cup C={1,2,5,6,8,9}\) है। (A) से (1,2,5,6) हटाने पर (3,4) बचते हैं।
