यदि \(x\in\mathbb{Z}\) और \(-12<3x\le 15\), तो संख्या रेखा पर कितने पूर्णांक बिंदु होंगे?
If \(x\in\mathbb{Z}\) and \(-12<3x\le 15\), how many integer points will be on the number line?
Explanation opens after your attempt
Correct Answer
B. (9)
Concept
Dividing gives \(-4<x\le5\), so integers from (-3) to (5) total (9). In exams, do not count an open lower boundary.
Why this answer is correct
The correct answer is B. (9). Dividing gives \(-4<x\le5\), so integers from (-3) to (5) total (9). In exams, do not count an open lower boundary.
Exam Tip
भाग देने पर \(-4<x\le5\), इसलिए पूर्णांक (-3) से (5) तक कुल (9) हैं। परीक्षा में open lower boundary को count न करें।
