यदि (n(U)=64) और (n(A)=3n\(A^c\)) है, तो (n\(A^c\)) कितना होगा?

If (n(U)=64) and (n(A)=3n\(A^c\)), what is (n\(A^c\))?

Explanation opens after your attempt
Correct Answer

A. (16)

Step 1

Concept

Let (n\(A^c\)=x), then (n(A)=3x). Thus (3x+x=64), giving (x=16).

Step 2

Why this answer is correct

The correct answer is A. (16). Let (n\(A^c\)=x), then (n(A)=3x). Thus (3x+x=64), giving (x=16).

Step 3

Exam Tip

मान लें (n\(A^c\)=x), तब (n(A)=3x)। इसलिए (3x+x=64) से (x=16) मिलता है।
