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
A. (16)
Concept
Let (n\(A^c\)=x), then (n(A)=3x). Thus (3x+x=64), giving (x=16).
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).
Exam Tip
मान लें (n\(A^c\)=x), तब (n(A)=3x)। इसलिए (3x+x=64) से (x=16) मिलता है।
