यदि (n(U)=16) और (n(A)=n\(A^c\)) है, तो (n(A)) कितना होगा?
If (n(U)=16) and (n(A)=n\(A^c\)), what is (n(A))?
Explanation opens after your attempt
A. (8)
Concept
(A) and \(A^c\) together form (U), and their counts are equal. Hence \(16\div 2=8\).
Why this answer is correct
The correct answer is A. (8). (A) and \(A^c\) together form (U), and their counts are equal. Hence \(16\div 2=8\).
Exam Tip
(A) और \(A^c\) मिलकर (U) बनाते हैं और दोनों की संख्या बराबर है। इसलिए \(16\div 2=8\) होगा।
