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
Correct Answer

A. (12)

Step 1

Concept

(A) and \(A^c\) together form (U), and both have equal size. Hence \(24\div 2=12\).

Step 2

Why this answer is correct

The correct answer is A. (12). (A) and \(A^c\) together form (U), and both have equal size. Hence \(24\div 2=12\).

Step 3

Exam Tip

(A) और \(A^c\) मिलकर (U) बनाते हैं और दोनों बराबर हैं। इसलिए \(24\div 2=12\) होगा।
