यदि \(A=\{1,2,3,4,5\}\), \(B=\{3,4,5,6\}\) और \(C=\{5,6,7\}\) है, तो \(A\cap(B-C)\) क्या है?
If \(A=\{1,2,3,4,5\}\), \(B=\{3,4,5,6\}\), and \(C=\{5,6,7\}\), what is \(A\cap(B-C)\)?
Explanation opens after your attempt
A. ( {3,4} )
Concept
First (B-C={3,4}), then the common part with (A) is ({3,4}). Always solve the operation inside brackets first.
Why this answer is correct
The correct answer is A. ( {3,4} ). First (B-C={3,4}), then the common part with (A) is ({3,4}). Always solve the operation inside brackets first.
Exam Tip
पहले (B-C={3,4}) है, फिर (A) के साथ सामान्य भाग ({3,4}) मिलता है। कोष्ठक वाली क्रिया हमेशा पहले करें।
