यदि \(A\cap B\ne\varnothing\) और \(A\setminus B=\varnothing\) है, तो कौन-सा निष्कर्ष सही है?
If \(A\cap B\ne\varnothing\) and \(A\setminus B=\varnothing\), which conclusion is correct?
Explanation opens after your attempt
Correct Answer
A. \(A\subseteq B\) और \(A\ne\varnothing\)
Concept
\(A\setminus B=\varnothing\) gives \(A\subseteq B\). \(A\cap B\ne\varnothing\) shows that (A) is not empty.
Why this answer is correct
The correct answer is A. \(A\subseteq B\) और \(A\ne\varnothing\). \(A\setminus B=\varnothing\) gives \(A\subseteq B\). \(A\cap B\ne\varnothing\) shows that (A) is not empty.
Exam Tip
\(A\setminus B=\varnothing\) से \(A\subseteq B\) है। \(A\cap B\ne\varnothing\) बताता है कि (A) खाली नहीं है।
