यदि \(A\subseteq B\subseteq U\), (n(U)=150), (n(A)=64) और (n(B)=97), तो (n\(A'\cap B\)) क्या है?
If \(A\subseteq B\subseteq U\), (n(U)=150), (n(A)=64), and (n(B)=97), what is (n\(A'\cap B\))?
Explanation opens after your attempt
Correct Answer
A. (33)
Concept
Since \(A\subseteq B\), \(A'\cap B=B-A\). Therefore the count is (97-64=33).
Why this answer is correct
The correct answer is A. (33). Since \(A\subseteq B\), \(A'\cap B=B-A\). Therefore the count is (97-64=33).
Exam Tip
क्योंकि \(A\subseteq B\), \(A'\cap B=B-A\) होगा। इसलिए संख्या (97-64=33) है।
