Mathematics Answer, Explanation and Revision Hints
\(यदि (J={x:x\) एक पूर्ण संख्या है और 4<x\leq 7}) है, तो (J) क्या है? \(/ If (J={x:x\) is a whole number and \(4<x\leq 7}), what is (J)\)?
Correct Answer: A. \(J=\{5,6,7\}\). Explanation: चरण 1: (4<x) के कारण (4) शामिल नहीं है। चरण 2: \(x\leq 7\) के कारण (7) शामिल है, इसलिए अवयव (5,6,7) हैं। चरण 3: दोनों असमानता चिह्नों को अलग-अलग पढ़ें। / Step 1: Because of (4<x), (4) is not included. Step 2: Because of \(x\leq 7\), (7) is included, so the elements are (5,6,7). Step 3: Read both inequality symbols separately.
