Correct Answer - Option 3 : 17%
Given
An article was purchased for Rs.7000.After that price was marked by 30%.
Discount of 10% was given on mark up price.
Formula used
MP(1 - D/100) = SP
MP = Marked Price
SP = Selling Price
D = Discount
Calculation
Marked price = Rs.7000 + 7000 × 30/100
⇒ MP = Rs. 9100
⇒ SP = MP(1 - D/100)
⇒ SP = 9100 × 90/100
⇒ SP = Rs.8190
⇒ Profit = 8190 - 7000
⇒ Profit% = (1190/7000) × 100
∴ Profit% is 17%
