यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6,8\}\) और \(C=\{1,4,6\}\) है, तो (A-\(B\cap C\)) क्या है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6,8\}\), and \(C=\{1,4,6\}\), what is (A-\(B\cap C\))?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3,5} )
Concept
First \(B\cap C={4,6}\), then removing these from (A) leaves ({1,2,3,5}). In difference, remove elements only from the first set.
Why this answer is correct
The correct answer is A. ( {1,2,3,5} ). First \(B\cap C={4,6}\), then removing these from (A) leaves ({1,2,3,5}). In difference, remove elements only from the first set.
Exam Tip
पहले \(B\cap C={4,6}\) है, फिर (A) से इन्हें हटाने पर ({1,2,3,5}) बचता है। अंतर में पहले समुच्चय से ही अवयव हटाएं।
