Correct Answer - Option 1 : 575

**Given:**

The marked price of an article is 30% above the cost price

**Calculation:**

Let us assume cost price of article is C

⇒ Selling price of article = (1.3C) × (100 - X)/100

⇒ The selling price of article = 1.17C

⇒ (1.3C) × (100 - X)/100 = 1.17C

⇒ 130 - 1.3X = 117

⇒ X = 10%

⇒ The selling price of another article = 500 × {100 + (X + 5)} = 500 × (100 + 15) = 575

**∴ The required result will be 575.**
