Study the given graph and answer the question that follows.

By what percentage is 80% of the total export of sugar in 2016, 2017 and 2019 more than the total production in 2015 and 2018 (correct to one decimal place)?

6.3%

Total export of sugar in 2016, 2017 and 2019 = 270 + 360 + 380 = 1010

80% of Total export of sugar in 2016, 2017 and 2019 = \(\frac{4}{5}\) × 1010 

= 808

Total production in 2015 and 2018 = 320 + 440 = 760

Required percentage = \(\frac{1010 - 760 }{760}\) × 100

= \(\frac{ 48 }{760}\) × 100

= 6.3%
