The price of one pen is \(x\) rupees. The total cost of four pens is not more than 100 rupees. Which inequality gives the solution for \(x\)?

Answer and explanation

Correct answer: \(x\le 25\)

The cost of four pens is \(4x\) rupees. “Not more than 100” means \(4x\le 100\). Dividing both sides by the positive number 4 gives \(x\le 25\), so option A is correct. In exams, remember that “not more than” indicates the \(\le\) sign, not the strict sign \(<\).
