Study the given graph and answer the question that follows.

By what percentage is the average expenditure of the company in 2014, 2016 and 2018 less than the revenue in 2017?

38.75%

Average expenditure of the company in 2014, 2016 and 2018

= \(\frac{225+330+180 }{3}\)

= \(\frac{ 735 }{3}\)

= 245

Revenue in 2017  = 400

Required percentage = \(\frac{400-245 }{400}\) × 100

= \(\frac{ 155}{400}\) × 100

= 38.75%
