यदि \(A=\{2,3,5,7,11\}\) और \(B={x:x\in A,;x+1\in A}\), तो \(A\setminus B\) क्या है?
If \(A=\{2,3,5,7,11\}\) and \(B={x:x\in A,;x+1\in A}\), what is \(A\setminus B\)?
Explanation opens after your attempt
Correct Answer
A. ({3,5,7,11})
Concept
Only (2+1=3) belongs to (A), so \(B=\{2\}\). Therefore \(A\setminus B={3,5,7,11}\).
Why this answer is correct
The correct answer is A. ({3,5,7,11}). Only (2+1=3) belongs to (A), so \(B=\{2\}\). Therefore \(A\setminus B={3,5,7,11}\).
Exam Tip
केवल (2+1=3) सेट (A) में है, इसलिए \(B=\{2\}\) है। अतः \(A\setminus B={3,5,7,11}\) है।
