यदि \(A\subseteq B\), (n(B)=83), (n(A)=47) और (n(U)=120) है, तो (n(B-A)) कितना होगा?
If \(A\subseteq B\), (n(B)=83), (n(A)=47) and (n(U)=120), then what is (n(B-A))?
Explanation opens after your attempt
Correct Answer
A. (36)
Concept
Since \(A\subseteq B\), (B-A=83-47=36). In a subset Venn diagram, the smaller circle lies inside the larger one.
Why this answer is correct
The correct answer is A. (36). Since \(A\subseteq B\), (B-A=83-47=36). In a subset Venn diagram, the smaller circle lies inside the larger one.
Exam Tip
क्योंकि \(A\subseteq B\), इसलिए (B-A=83-47=36) होगा। उपसमुच्चय वाले वेन आरेख में छोटा वृत्त बड़े के अंदर होता है।
