यदि \(A\subseteq B\) और \(B-A=\emptyset\), तो कौन सा निष्कर्ष सही है?
If \(A\subseteq B\) and \(B-A=\emptyset\), which conclusion is correct?
Explanation opens after your attempt
A. (A=B)
Concept
We have \(A\subseteq B\), and (B) has no element outside (A). Therefore the two sets are equal.
Why this answer is correct
The correct answer is A. (A=B). We have \(A\subseteq B\), and (B) has no element outside (A). Therefore the two sets are equal.
Exam Tip
\(A\subseteq B\) है और (B) में (A) के बाहर कोई सदस्य नहीं है। इसलिए दोनों बराबर हैं।
