यदि \(A=\{1,2,3,4\}\) और \(B=\{2,4,6,8\}\) है, तो कौन सा अवयव (A-B) में है?
If \(A=\{1,2,3,4\}\) and \(B=\{2,4,6,8\}\), which element is in (A-B)?
Explanation opens after your attempt
C. (3)
Concept
(3) is in (A) but not in (B), so \(3\in A-B\). In difference, keep elements of the first set not in the second.
Why this answer is correct
The correct answer is C. (3). (3) is in (A) but not in (B), so \(3\in A-B\). In difference, keep elements of the first set not in the second.
Exam Tip
(3) (A) में है लेकिन (B) में नहीं है, इसलिए \(3\in A-B\) है। अंतर में केवल पहले समुच्चय के बाहर वाले सामान्य अवयव हटते हैं।
