\(यदि (C_1={x:x\) संख्या 15 से छोटी धनात्मक सम भाज्य संख्या है\(}), तो (C_1) क्या होगा\)?
\(If (C_1={x:x\) is a positive even composite number less than \(15}), what is (C_1)\)?
Explanation opens after your attempt
A. \(C_1={4,6,8,10,12,14}\)
Concept
Positive even numbers less than (15) are (2,4,6,8,10,12,14).
Why this answer is correct
(2) is prime, not composite, so it is removed.
Exam Tip
When two properties are given, apply both together. चरण 1: धनात्मक सम संख्याएँ (2,4,6,8,10,12,14) हैं। चरण 2: (2) अभाज्य है, भाज्य नहीं; इसलिए उसे हटाएँ। चरण 3: जब दो गुण एक साथ दिए हों, तो दोनों शर्तें साथ-साथ लागू करें।
