A shopkeeper marked an item 50% above the cost price and gave a 10% discount on the marked price. If the final selling price was ₹540, find the cost price.

1. ₹ 350
2. ₹ 400
3. ₹ 450
4. ₹ 380

Correct answer: ₹ 400

Solution

If the selling price is ₹540 after a 10% discount, then the marked price is \(540/0.9 = 600\). Since the marked price is 50% above cost price, \(600 = 1.5 \times CP\), so \(CP = 400\).
