यदि (n\(A\cup B\)=126), (n(A-B)=48) और (n(B-A)=41) है, तो (n\(A\cap B\)) कितना है?
If (n\(A\cup B\)=126), (n(A-B)=48) and (n(B-A)=41), then what is (n\(A\cap B\))?
Explanation opens after your attempt
A. (37)
Concept
The union is the sum of three disjoint parts, so the common part is (126-48-41=37). Count each Venn region once.
Why this answer is correct
The correct answer is A. (37). The union is the sum of three disjoint parts, so the common part is (126-48-41=37). Count each Venn region once.
Exam Tip
संघ तीन अलग भागों का योग है, इसलिए साझा भाग (126-48-41=37) है। वेन आरेख में हर क्षेत्र एक बार गिनें।
