Which of the following values is a solution of the inequality \(3x\le 12\)?निम्नलिखित में से कौन-सा मान असमानता \(3x\le 12\) का एक हल है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 44
Substituting \(x=4\) gives \(3\times4=12\), so \(12\le12\) is true. In contrast, \(x=5\) gives \(15\le12\), which is false. In an exam, test each option by substituting its value directly into the inequality.असमानता \(3x\le 12\) में \(x=4\) रखने पर \(3\times4=12\), इसलिए \(12\le12\) सत्य है। जबकि \(x=5\) रखने पर \(15\le12\) असत्य होता है। परीक्षा में किसी विकल्प को जाँचने के लिए उसका मान सीधे असमानता में रखकर तुलना करें।
