Which company has the minimum average (in thousands) of manufacturing computers from 2010 to 2014?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. A.
Average computer manufacturing of A company = (240 + 300 + 1250 + 470 + 320)/5 = 2580/5 = 516
Average computer manufacturing of B company = (120 + 530 + 650 + 320 + 1070)/5 = 2690/5 = 538
Average computer manufacturing of C company = (270 + 490 + 430 + 1180 + 550)/5 = 2920/5 = 584
Average computer manufacturing of D company = (280 + 650 + 710 + 890 + 480)/5 = 3010/5 = 602
Hence, company A has the minimum average.
