यदि (n(U)=24) और (n(A)=n\(A^c\)) है, तो (n(A)) कितना होगा?
If (n(U)=24) and (n(A)=n\(A^c\)), what is (n(A))?
Explanation opens after your attempt
A. (12)
Concept
(A) and \(A^c\) together form (U), and both have equal size. Hence \(24\div 2=12\).
Why this answer is correct
The correct answer is A. (12). (A) and \(A^c\) together form (U), and both have equal size. Hence \(24\div 2=12\).
Exam Tip
(A) और \(A^c\) मिलकर (U) बनाते हैं और दोनों बराबर हैं। इसलिए \(24\div 2=12\) होगा।
