\(यदि (A={x:x\) 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
B. (5)
Concept
\(2\leq x\leq 6\) में (2) और (6) दोनों शामिल हैं। / In \(2\leq x\leq 6\), both (2) and (6) are included.
Why this answer is correct
अवयव (2,3,4,5,6) हैं, जिनकी संख्या (5) है। / The elements are (2,3,4,5,6), so there are (5) elements.
Exam Tip
गिनते समय दोनों सीमाओं को शामिल करना न भूलें। / While counting, do not forget to include both endpoints.
