यदि \(A=\{1,2,3,4,5,6,7,8\}\), \(B=\{2,4,6,8\}\) और \(C=\{1,2,3,4\}\) हैं, तो \(B\setminus C\) क्या है?
If \(A=\{1,2,3,4,5,6,7,8\}\), \(B=\{2,4,6,8\}\), and \(C=\{1,2,3,4\}\), what is \(B\setminus C\)?
Explanation opens after your attempt
Correct Answer
A. ( {6,8} )
Concept
The common elements (2) and (4) of (C) are removed from (B). Hence \(B\setminus C={6,8}\).
Why this answer is correct
The correct answer is A. ( {6,8} ). The common elements (2) and (4) of (C) are removed from (B). Hence \(B\setminus C={6,8}\).
Exam Tip
(B) से (C) के सामान्य अवयव (2) और (4) हटते हैं। इसलिए \(B\setminus C={6,8}\)।
