यदि \(A\subseteq B\subseteq C\), (n(C)=118), (n(B)=73) और (n(A)=29) है, तो (n(C-A)) कितना होगा?
If \(A\subseteq B\subseteq C\), (n(C)=118), (n(B)=73), and (n(A)=29), what is (n(C-A))?
Explanation opens after your attempt
Correct Answer
C. (89)
Concept
Since (A) lies fully inside (C), (n(C-A)=118-29=89). In a nested Venn diagram, subtract only the set being removed.
Why this answer is correct
The correct answer is C. (89). Since (A) lies fully inside (C), (n(C-A)=118-29=89). In a nested Venn diagram, subtract only the set being removed.
Exam Tip
क्योंकि (A) पूरा (C) में है, इसलिए (n(C-A)=118-29=89)। nested वेन आरेख में जिस समुच्चय को हटाना हो केवल वही घटाएं।
