किस शर्त पर दो समुच्चय (A) और (B) बराबर कहलाते हैं?
Under which condition are two sets (A) and (B) called equal?
Explanation opens after your attempt
Correct Answer
A. \(A\subseteq B\) और \(B\subseteq A\)\(A\subseteq B\) and \(B\subseteq A\)
Concept
If each set is a subset of the other, every member matches. Equal cardinality alone is not enough.
Why this answer is correct
The correct answer is A. \(A\subseteq B\) और \(B\subseteq A\) / \(A\subseteq B\) and \(B\subseteq A\). If each set is a subset of the other, every member matches. Equal cardinality alone is not enough.
Exam Tip
दोनों दिशाओं में उपसमुच्चय संबंध होने पर हर सदस्य समान होता है। केवल सदस्यों की संख्या बराबर होना काफी नहीं है।
