यदि \(A=\{1,2\}\) और \(B={1,2,\emptyset}\) है तो कौन सा कथन सही है?
If \(A=\{1,2\}\) and \(B={1,2,\emptyset}\) then which statement is correct?
Explanation opens after your attempt
Correct Answer
B. \(A\subset B\) और \(A\ne B\)\(A\subset B\) and \(A\ne B\)
Concept
Both elements of (A) are in (B) but (B) has the extra element \(\emptyset\). In exams an extra element breaks equality.
Why this answer is correct
The correct answer is B. \(A\subset B\) और \(A\ne B\) / \(A\subset B\) and \(A\ne B\). Both elements of (A) are in (B) but (B) has the extra element \(\emptyset\). In exams an extra element breaks equality.
Exam Tip
(A) के दोनों तत्व (B) में हैं पर (B) में अतिरिक्त तत्व \(\emptyset\) है। परीक्षा में अतिरिक्त तत्व बराबरी को तोड़ देता है।
