असमानता \(3\leq \frac{x+2}{5}\leq 6\) का हल क्या है?
What is the solution of \(3\leq \frac{x+2}{5}\leq 6\)?
Explanation opens after your attempt
A. \(13\leq x\leq 28\)
Concept
Multiplying by (5) gives \(15\leq x+2\leq 30\). Subtracting (2) gives \(13\leq x\leq 28\).
Why this answer is correct
The correct answer is A. \(13\leq x\leq 28\). Multiplying by (5) gives \(15\leq x+2\leq 30\). Subtracting (2) gives \(13\leq x\leq 28\).
Exam Tip
(5) से गुणा करने पर \(15\leq x+2\leq 30\) मिलता है। फिर (2) घटाने पर \(13\leq x\leq 28\) मिलता है।
