Question
Total number of HP laptops sold in 2015 and 2016
together is approximately what percent more of the total number of HP laptops sold in 2017 and 2018 together? Study the following graph carefully and answer the given questions: The graph shows the number of laptops sold (in thousands) in the following given six years.Solution
Total number of HP laptops sold in 2015 and 2016 together = 8 + 6 = 14 thousands Total number of HP laptops sold in 2017 and 2018 together = 2 + 7 = 9 thousands Required % = [(14 – 9)/9] × 100 = 55.55% ≈ 56% approx.
