Question 64
The bar chart given below shows the annual production (in 1000 tonnes) of coffee of a country for years 2009 to 2013.
What is the average production (in 1000 tonnes) of coffee from year 2009 to 2011?
Solution
Production of coffee in 2009 = 800000 tonnes
Production of coffee in 2010 = 1200000 tonnes
Production of coffee in 2011 = 1500000 tonnes
Average production = $$\dfrac{800000+1200000+1500000}{3} = \dfrac{3500000}{3} = 1166666.67$$ tonnes
Average production in 1000 tonnes = 1166.67
