यदि (A=(-2,3]), तो कौन-सा कथन गलत है?
If (A=(-2,3]), which statement is false?
Explanation opens after your attempt
C. \(-2\in A\)
Concept
In ((-2,3]), (-2) is excluded and (3) is included.
Why this answer is correct
(0) and (2.5) lie inside the interval, so they are included.
Exam Tip
Pay special attention to endpoints when finding a false statement. चरण 1: ((-2,3]) में (-2) शामिल नहीं है और (3) शामिल है। चरण 2: (0) और (2.5) बीच में हैं, इसलिए वे शामिल हैं। चरण 3: गलत कथन खोजते समय छोरों पर विशेष ध्यान दें।
