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