यदि केवल \(A\cap B\) में (14), केवल \(B\cap C\) में (12), केवल \(C\cap A\) में (15) और \(A\cap B\cap C\) में (8) तत्व हैं, तो (n(\(A\cap B\)\cup\(B\cap C\)\cup\(C\cap A\))) कितना है?
If only \(A\cap B\) has (14), only \(B\cap C\) has (12), only \(C\cap A\) has (15), and \(A\cap B\cap C\) has (8) elements, then what is (n(\(A\cap B\)\cup\(B\cap C\)\cup\(C\cap A\)))?
Explanation opens after your attempt
A. (49)
Concept
This region is the part belonging to at least two sets, so (14+12+15+8=49). Add the centre only once.
Why this answer is correct
The correct answer is A. (49). This region is the part belonging to at least two sets, so (14+12+15+8=49). Add the centre only once.
Exam Tip
यह क्षेत्र कम से कम दो समुच्चयों का भाग है, इसलिए (14+12+15+8=49) है। केंद्र को केवल एक बार जोड़ें।
