Given:
Company D:
2011 = 78, 2012 = 95, 2013 = 13, 2014 = 43, 2015 = 38
Company E:
2011 = 44, 2012 = 91, 2013 = 31, 2014 = 86, 2015 = 57
Formula:
Difference = total sale of company E – total sale of company D

total sale of company D = 267
total sale of company E = 309
Difference = 309 – 267 = 42
∴ Required difference is 42.
