यदि \(A\subseteq B\), (n(A)=34) और (n(B)=82) है, तो (n(B-A)) कितना होगा?
If \(A\subseteq B\), (n(A)=34), and (n(B)=82), what is (n(B-A))?
Explanation opens after your attempt
Correct Answer
A. (48)
Concept
Since (A) lies completely inside (B), (n(B-A)=82-34=48). In a subset case, the smaller circle lies inside the larger one.
Why this answer is correct
The correct answer is A. (48). Since (A) lies completely inside (B), (n(B-A)=82-34=48). In a subset case, the smaller circle lies inside the larger one.
Exam Tip
क्योंकि (A) पूरा (B) में है, इसलिए (n(B-A)=82-34=48)। उपसमुच्चय में छोटा वृत्त बड़े के अंदर होता है।
