यदि \(A=\{1,3,5,7,9\}\), \(B=\{2,3,5,8\}\) और \(C=\{3,4,5,6\}\) है, तो (A-\(B\cap C\)) क्या है?
If \(A=\{1,3,5,7,9\}\), \(B=\{2,3,5,8\}\), and \(C=\{3,4,5,6\}\), what is (A-\(B\cap C\))?
Explanation opens after your attempt
A. ( {1,7,9} )
Concept
\(B\cap C={3,5}\). Removing these from (A) gives ({1,7,9}).
Why this answer is correct
The correct answer is A. ( {1,7,9} ). \(B\cap C={3,5}\). Removing these from (A) gives ({1,7,9}).
Exam Tip
\(B\cap C={3,5}\) है। इन्हें (A) से हटाने पर ({1,7,9}) मिलता है।
