\(यदि (M={x \in \mathbb{N}:x\leq 50\) और x 10 का गुणज है}), तो (M) में कितने सदस्य हैं?
\(If (M={x \in \mathbb{N}:x\leq 50\) and x is a multiple of 10}), how many elements are in (M)?
Explanation opens after your attempt
B. (5)
Concept
List multiples of (10) up to (50).
Why this answer is correct
They are (10,20,30,40,50), so there are (5) elements.
Exam Tip
When the symbol is \(\leq\), include the endpoint. चरण 1: (50) तक (10) के गुणज लिखें। चरण 2: वे (10,20,30,40,50) हैं, इसलिए कुल (5) सदस्य हैं। चरण 3: \(\leq\) चिन्ह हो तो अंतिम सीमा को शामिल करना न भूलें।
