यदि \(A=\{1,2,3,4,5\}\), \(B=\{2,4,6,8\}\) और \(C=\{1,4,7,8\}\) हैं, तो (A\cap\(B\cup C\)) क्या है?
If \(A=\{1,2,3,4,5\}\), \(B=\{2,4,6,8\}\), and \(C=\{1,4,7,8\}\), what is (A\cap\(B\cup C\))?
Explanation opens after your attempt
A. ({1,2,4})
Concept
First \(B\cup C={1,2,4,6,7,8}\). Its intersection with (A) is ({1,2,4}).
Why this answer is correct
The correct answer is A. ({1,2,4}). First \(B\cup C={1,2,4,6,7,8}\). Its intersection with (A) is ({1,2,4}).
Exam Tip
पहले \(B\cup C={1,2,4,6,7,8}\) मिलता है। इसके साथ (A) का प्रतिच्छेद ({1,2,4}) है।
