यदि \(A={x\in\mathbb{N}: x\le 30,\ 2\mid x}\) और \(B={x\in\mathbb{N}: x\le 30,\ 3\mid x}\), तो \(A\cap B\) क्या है?
If \(A={x\in\mathbb{N}: x\le 30,\ 2\mid x}\) and \(B={x\in\mathbb{N}: x\le 30,\ 3\mid x}\), what is \(A\cap B\)?
Explanation opens after your attempt
A. ({6,12,18,24,30})
Concept
Numbers divisible by both (2) and (3) are divisible by (6). Up to (30), these are ({6,12,18,24,30}).
Why this answer is correct
The correct answer is A. ({6,12,18,24,30}). Numbers divisible by both (2) and (3) are divisible by (6). Up to (30), these are ({6,12,18,24,30}).
Exam Tip
जो संख्याएं (2) और (3) दोनों से विभाज्य हैं, वे (6) से विभाज्य हैं। (30) तक ऐसी संख्याएं ({6,12,18,24,30}) हैं।
