Question
Marked price and cost price of an article are in the
ratio 7:4, respectively. If the article was sold at discount of 20%, then find the gain percentage.Solution
Let the marked price of the article be Rs. '7x' So, cost price of the article = 7x X (4/7) = Rs. '4x' Selling price of the article = 7x X 0.8 = Rs. '5.6x' So, gain earned = 5.6x - 4x = Rs. '1.6x' So, gain percentage = (1.6x/4x) X 100 = 40%
