यदि (n(A)=32) और (n\(A\cap B\)=14) है, तो वेन आरेख में केवल (A) वाले तत्व कितने होंगे?
If (n(A)=32) and (n\(A\cap B\)=14), then how many elements are only in (A) in the Venn diagram?
Explanation opens after your attempt
A. (18)
Concept
Only (A) is (n(A)-n\(A\cap B\)=32-14=18). Drawing the diagram and subtracting the middle part is the safest method.
Why this answer is correct
The correct answer is A. (18). Only (A) is (n(A)-n\(A\cap B\)=32-14=18). Drawing the diagram and subtracting the middle part is the safest method.
Exam Tip
केवल (A) का भाग (n(A)-n\(A\cap B\)=32-14=18) है। आरेख बनाकर मध्य भाग घटाना सबसे सुरक्षित तरीका है।
