The marked price of an article is 30% above the cost price, and the article is sold at 10% less than the marked price. The profit percentage is:

Correct option is D

Given:
Marked Price (MP) is 30% above Cost Price (CP)
Selling Price (SP) is 10% less than MP
Formula Used:
$$\text{Profit \%} = \frac{SP - CP}{CP} \times 100$$​​
Solution:
Let CP of an article = 100 
Marked Price (MP) is 30% above Cost Price (CP)
MP = CP × 1.30 = 100 × 1.30 = 130
Selling Price (SP) is 10% less than MP
SP = MP × 0.90 = 130 × 0.90 = 117
Profit = SP – CP = 117 – 100 = 17
Profit % = $$\frac{17}{100}$$​ × 100 = 17%
