  2. B10%
  3. C15%
  4. D12%

Answer: A. 18%

Explanation

Given: First discount is 10% List price = ₹ 175 Selling price = ₹ 129.15 Concept used: Selling price = List price × (100 - discount)% Calculation: After 1st discount amount = 175 × (90/100) ⇒ 157.5 Discount amount = 157.5 - 129.15 ⇒ 28.35 Now, Discount % = (28.35/157.5) × 100 ⇒ 18% ∴ The second discount is 18 %.
