Answers
Production of company 1 in 2011 = 0.6 × 20000 = 12000
Production of company 1 in 2012 = 0.9 × 20000 = 18000
Production of company 1 in 2013 = 0.7 × 20000 = 14000
Production of company 1 in 2014 = 0.9 × 20000 = 18000
Production of company 1 in 2015 = 1.3 × 20000 = 26000
Production of company 1 in 2016 = 1.3 × 20000 = 26000
Total production of company 1 = 114000
Production of company 2 in 2011 = 0.8 × 10000 = 8000
Production of company 2 in 2012 = 0.75 × 10000 = 7500
Production of company 2 in 2013 = 0.4 × 10000 = 4000
Production of company 2 in 2014 = 1.3 × 10000 = 13000
Production of company 2 in 2015 = 1.45 × 10000 = 14500
Production of company 2 in 2016 = 1.1 × 10000 = 11000
Total production of company 2 = 58000
Required average difference = (114000-58000)/6
= 9333.33
hope it helps
