Study the given graph and answer the question that follows.

By what percentage is the average export of sugar in 2016, 2017 and 2018 less than the production in 2017?

22.5%

Average export of sugar in 2016, 2017 and 2018 =  \(\frac{270+360+300 }{3}\)

=  \(\frac{ 930}{3}\)

= 310

Production in 2017 = 400

Required percentage = \(\frac{400 - 310 }{400}\) × 100

= \(\frac{90 }{4}\)

= 22.5%
