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%
