यदि (n(A)=92), (n(B)=85), (n(C)=78), (n\(A\cap B\)=37), (n\(B\cap C\)=34), (n\(C\cap A\)=29) और (n\(A\cap B\cap C\)=16) है, तो केवल \(B\cap C\) में कितने तत्व हैं?

If (n(A)=92), (n(B)=85), (n(C)=78), (n\(A\cap B\)=37), (n\(B\cap C\)=34), (n\(C\cap A\)=29) and (n\(A\cap B\cap C\)=16), then how many elements are only in \(B\cap C\)?

Explanation opens after your attempt
Correct Answer

A. (18)

Step 1

Concept

Only \(B\cap C\) has (34-16=18) elements. A two-set intersection also includes the central three-set region.

Step 2

Why this answer is correct

The correct answer is A. (18). Only \(B\cap C\) has (34-16=18) elements. A two-set intersection also includes the central three-set region.

Step 3

Exam Tip

केवल \(B\cap C\) में (34-16=18) तत्व होंगे। दो-समुच्चय प्रतिच्छेद में तीनों वाला केंद्र भी शामिल होता है।
