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