यदि (n(U)=180), (n(A)=109), (n(B)=97) है, तो (n\(A\cup B\)) का न्यूनतम संभव मान कितना है?
If (n(U)=180), (n(A)=109), (n(B)=97), then what is the minimum possible value of (n\(A\cup B\))?

Correct Answer
A. (109)
Concept
The minimum union can equal the larger set, which is (109). This happens when the smaller set lies inside the larger set.
Why this answer is correct

Exam Tip
संघ का न्यूनतम मान बड़े समुच्चय के बराबर हो सकता है, यानी (109)। ऐसा तब होगा जब छोटा समुच्चय बड़े में समा जाए।
