The line chart given below shows the marked price and selling price of 7 articles.

The total marked price of all the articles is how much percent more than the total selling price of all articles?

78.37 percent

Total marked price = 1300 + 900 + 1100 + 800 + 600 + 700 + 1200 = 6600

Total selling price = 700 + 400 + 700 + 600 + 500 + 400 + 400 = 3700

Required percentage = \(\frac{6600 - 3700}{3700}\) × 100

= \(\frac{2900}{3700}\) × 100

= 78.37%
