Question : The marked price of an article is twice the cost price. For a gain of 30%, what should be the discount percentage?
Option 1: 30%
Option 2: 35%
Option 3: 25%
Option 4: 40%
Correct Answer: 35%
Solution :
Let the cost price be Rs. 100.
The selling price when profit is 30% = 100 + 30% of 100 = Rs. 130
The marked price is twice the cost price = Rs. 200
Discount = 200 – 130 = Rs 70
Discount percentage = $\frac{\text{Discount} }{\text{Marked price}}\times 100$
= $\frac{70 }{200}\times 100 = 35$%
Hence, the correct answer is 35%.
