असमानता \(\frac{7-2x}{5}\le \frac{3x+1}{10}\) का हल चुनिए।

Choose the solution of \(\frac{7-2x}{5}\le \frac{3x+1}{10}\).

Explanation opens after your attempt
Correct Answer

A. \(x\ge \frac{13}{7}\)

Step 1

Concept

Multiplying by (10) gives \(14-4x\le 3x+1\). Thus \(13\le 7x\), so \(x\ge \frac{13}{7}\).

Step 2

Why this answer is correct

The correct answer is A. \(x\ge \frac{13}{7}\). Multiplying by (10) gives \(14-4x\le 3x+1\). Thus \(13\le 7x\), so \(x\ge \frac{13}{7}\).

Step 3

Exam Tip

(10) से गुणा करने पर \(14-4x\le 3x+1\) मिलता है। इससे \(13\le 7x\), अतः \(x\ge \frac{13}{7}\)।
