यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,3\}\) और \(C=\{5,6,7\}\) है, तो (A-\(B\cup C\)) क्या है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,3\}\), and \(C=\{5,6,7\}\), what is (A-\(B\cup C\))?
Explanation opens after your attempt
A. ( {1,4} )
Concept
\(B\cup C={2,3,5,6,7}\), and removing these from (A) leaves ({1,4}). Solve the bracket first.
Why this answer is correct
The correct answer is A. ( {1,4} ). \(B\cup C={2,3,5,6,7}\), and removing these from (A) leaves ({1,4}). Solve the bracket first.
Exam Tip
\(B\cup C={2,3,5,6,7}\) है और (A) से इन्हें हटाने पर ({1,4}) बचता है। पहले कोष्ठक हल करें।
