Question
For all the years from 2015 to 2018, the average
production of B-type cars is how much less (in thousands) than that of the combined average production of A-type and C-type cars? Study the given table and answer the question that follows. The given table shows the production of three types of cars (A, B and C) manufactured (in thousands) by an automobile company over the years.Solution
Total production (in thousands):
A = 840 + 900 + 760 + 800 = 3300
B = 680 + 750 + 620 + 540 = 2590
C = 890 + 960 + 1000 + 1200 = 4050 Average: A = 3300 / 4 = 825, B = 2590 / 4 = 647.5 & C = 4050 / 4 = 1012.5 Combined average of A and C = (825 + 1012.5)/2 = 1837.5/2 = 918.75 Difference = 918.75 − 647.5 = 271.25
