\(यदि (A={x:x\) एक प्राकृतिक संख्या है और \(2\leq x\leq 6}) है, तो (A) में कितने अवयव हैं\)?

\(If (A={x:x\) is a natural number and \(2\leq x\leq 6}), how many elements are in (A)\)?

Explanation opens after your attempt
Correct Answer

B. (5)

Step 1

Concept

In \(2\leq x\leq 6\), both (2) and (6) are included.

Step 2

Why this answer is correct

The elements are (2,3,4,5,6), so there are (5) elements.

Step 3

Exam Tip

While counting, do not forget to include both endpoints. चरण 1: \(2\leq x\leq 6\) में (2) और (6) दोनों शामिल हैं। चरण 2: अवयव (2,3,4,5,6) हैं, जिनकी संख्या (5) है। चरण 3: गिनते समय दोनों सीमाओं को शामिल करना न भूलें।
