\(यदि (C_1={x:x\) 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 \(15}), what is (C_1)\)?
Correct answer and explanation
A. \(C_1={4,6,8,10,12,14}\)
Concept
धनात्मक सम संख्याएँ (2,4,6,8,10,12,14) हैं। / Positive even numbers less than (15) are (2,4,6,8,10,12,14).
Why this answer is correct
(2) अभाज्य है, भाज्य नहीं; इसलिए उसे हटाएँ। / (2) is prime, not composite, so it is removed.
Exam Tip
जब दो गुण एक साथ दिए हों, तो दोनों शर्तें साथ-साथ लागू करें। / When two properties are given, apply both together.
