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?
Answer & explanation
Correct answer: option 3
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%
