Correct Answer - Option 3 :

15%
**Given:**

List price of an article = Rs. 8500 and two discount offered first one is 12% and second one we have to find. Also the selling price = Rs. 6358

**Calculation:**

List price = Rs. 8,500 and Discount = 12% (12% = -3/25 = 22/25)

⇒ After first discount price came down by = (8500) × 22/25 = 85 × 88 = Rs. 7480

⇒ As given selling price = Rs. 6,358

⇒ Discount given = Rs. (7480 - 6358) = Rs. 1122

**⇒ ****Discount is on the given List price = (1122/7480) × 100 = 15%.**
