The following graph shows the revenue generated by three companies A, B and C in different years.
What is the average of total revenue generated by company A in 2019, company B in 2018 and company C in 2016?
Revenue generated by company A in the year 2019 is given to be 440 million
Revenue generated by company B in the year 2018 is given to be 280 million
And finally, Revenue generated by company C in the year 2016 is given to be 450 million
Adding them up and dividing by 3 in order to get the average, we get $$\frac{440+280+450}{3}=\frac{1170}{3}=390$$
Therefore, Option C is the correct answer.
