यदि (n\(A\cup B\)=76), (n(A-B)=31) और (n(B-A)=27) है, तो (n\(A\cap B\)) कितना होगा?
If (n\(A\cup B\)=76), (n(A-B)=31) and (n(B-A)=27), then what is (n\(A\cap B\))?

Correct Answer
A. (18)
Concept
The union is the sum of three disjoint parts, so the intersection is (76-31-27=18). For region-based questions, split the Venn diagram into parts.
Why this answer is correct
The correct answer is A. (18). The union is the sum of three disjoint parts, so the intersection is (76-31-27=18). For region-based questions, split the Venn diagram into parts.
Exam Tip
संघ तीन अलग भागों का योग है, इसलिए प्रतिच्छेद (76-31-27=18) है। क्षेत्र आधारित प्रश्नों में वेन आरेख को भागों में बाँटें।
