Correct Answer - Option 2 : 20%

**Given:**

Marked price = Rs.480

Discount% = 10%

Profit% = 8%

**Formula Used:**

Discount% = (Marked price – Selling price)/Marked Price × 100

Profit% = (Selling price – cost price)/cost price × 100

**Calculation: **

10 = (480 – SP)/480 × 100

⇒ 48 = 480 – SP

⇒ SP = 480 – 48

⇒ SP = Rs432

Now, profit = 8%

8 = (432 – CP)/CP × 100

⇒ 8CP = (432 – CP) × 100

⇒ 8CP = 43200 – 100CP

⇒ 108CP = 43200

⇒ CP = 400

If no Discount is alowed, then SP will be 480.

∴ profit = 480 – 400 = 80

Profit% = 80/400 × 100 = 20%

**∴ If no discount is allowed, then his gain percent is 20%**
