यदि \(A\cap B=\varnothing\) और \(A\cup B=U\) है, तो (B) किसके बराबर होगा?
If \(A\cap B=\varnothing\) and \(A\cup B=U\), then (B) is equal to what?
Explanation opens after your attempt
A. \(A^c\)
Concept
If two sets are disjoint and together form (U), then they are complements of each other. Hence \(B=A^c\).
Why this answer is correct
The correct answer is A. \(A^c\). If two sets are disjoint and together form (U), then they are complements of each other. Hence \(B=A^c\).
Exam Tip
यदि दो समुच्चय असंबद्ध हों और मिलकर (U) बनाएं, तो वे एक-दूसरे के पूरक होते हैं। इसलिए \(B=A^c\) होगा।
