यदि \(A\cup B=A\cap B\) है, तो क्या निष्कर्ष निकलेगा?
If \(A\cup B=A\cap B\), what conclusion follows?
Explanation opens after your attempt
A. (A=B)
Concept
Always \(A\cap B\subseteq A\cup B\). They can be equal only when (A) and (B) are the same set.
Why this answer is correct
The correct answer is A. (A=B). Always \(A\cap B\subseteq A\cup B\). They can be equal only when (A) and (B) are the same set.
Exam Tip
सदैव \(A\cap B\subseteq A\cup B\) होता है। दोनों बराबर तभी हो सकते हैं जब (A) और (B) समान हों।
