यदि \(A=\{1,2,5,10\}\) और \(B=\{2,4,6,10\}\) है, तो कौन सा अवयव (A-B) में है?
If \(A=\{1,2,5,10\}\) and \(B=\{2,4,6,10\}\), which element is in (A-B)?
Explanation opens after your attempt
A. (1)
Concept
(1) is in (A) but not in (B), so \(1\in A-B\). Difference keeps non-common elements of the first set.
Why this answer is correct
The correct answer is A. (1). (1) is in (A) but not in (B), so \(1\in A-B\). Difference keeps non-common elements of the first set.
Exam Tip
(1) (A) में है लेकिन (B) में नहीं है, इसलिए \(1\in A-B\) है। अंतर में पहले समुच्चय के गैर-सामान्य अवयव रहते हैं।
