Correct Answer - Option 1 : 12.5%
Given:
If an article is sold at a discount of 30% to the marked price, it makes a loss of 20%.
Concept used:
Profit and Loss
Calculation:
Discount of 30% is offered on MP
MP : SP = 10 : 7
It makes a loss of 20%
CP : SP = 5 : 4
MP : SP : CP = 40 : 28 : 35
To break it even means no profit no loss
Discount Percentage = \(\frac{5}{{40}} \times 100 = 12.5\% \)
