असमानता \(7\le \frac{3x+2}{2}<16\) का संख्या रेखा पर सही interval कौन-सा है?
Which is the correct interval on the number line for \(7\le \frac{3x+2}{2}<16\)?
Explanation opens after your attempt
A. ([4,10))
Concept
Multiplying all parts by (2) gives \(14\le 3x+2<32\), so \(4\le x<10\). In exams, apply the same operation to all parts of a compound inequality.
Why this answer is correct
The correct answer is A. ([4,10)). Multiplying all parts by (2) gives \(14\le 3x+2<32\), so \(4\le x<10\). In exams, apply the same operation to all parts of a compound inequality.
Exam Tip
दोनों ओर (2) से गुणा करने पर \(14\le 3x+2<32\), इसलिए \(4\le x<10\)। परीक्षा में compound inequality में सभी हिस्सों पर समान operation करें।
