Study the given graph and answer the question that follows.

Total expenditure of the company in 2016, 2017 and 2018 is what percentage less than the total revenue in the given five years (correct to one decimal place)?

34.5%

Total expenditure of the company in 2016, 2017 and 2018 = 350 + 275 + 325 = 950

Total revenue in the given five years = 200 + 250 + 320 + 300 + 380 = 1450

Required percentage = \(\frac{1450 - 950 }{1450}\) × 100

= \(\frac{500}{1450}\) × 100

= 34.5%    (correct to one decimal place)
