Cost price of article = 48$
% of overhead cost = 30
Net profit = 12 $
We need to calculate % markup
Net profit as % of cost price = (12/48)*100 = 25%
Total markup should be = 25 + 30 = 55%
The purchase price of an article is $48. In order to include 30% of cost for overhead and to provide $12 of net profit, the markup should be
  * 15%
  * 25%
  * 35%
  * 40%
  * 55%
