(n(A-B)=16) और (n\(A\cap B\)=11) है। (n(A)) कितना होगा?
(n(A-B)=16) and (n\(A\cap B\)=11). What is (n(A))?
Explanation opens after your attempt
A. (27)
Concept
Whole (A) is made of two parts (A-B) and \(A\cap B\). Hence (n(A)=16+11=27).
Why this answer is correct
The correct answer is A. (27). Whole (A) is made of two parts (A-B) and \(A\cap B\). Hence (n(A)=16+11=27).
Exam Tip
पूरा (A) दो भागों (A-B) और \(A\cap B\) से बनता है। इसलिए (n(A)=16+11=27)।
