SSC CPO 13th-March-2019-Shift-2
Explanation:
- The shopkeeper applies a 30% discount to the marked price of Rs 480.
- This means the selling price is 70% of Rs 480: \(0.7 \times 480 = 336\).
- The selling price allows a 20% gain over the cost price.
- If the cost price is \(x\), then the selling price of Rs 336 corresponds to 120% of the cost price: \(1.2x = 336\).
- Solving for \(x\), gives \(x = \frac{336}{1.2} = 280\).
- Therefore, the cost price of the article is Rs 280.
