What is the difference between the average production of plant 1 and plant 2 during five years?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1600.
The average of plant 1 in 5 years = (35 + 43 + 48 + 32 + 42)/5 = 40000
The average of plant 2 in 5 years = (25 + 44 + 39 + 40 + 44)/5 = 38400
the difference between the average production of plant 1 and plant 2 = 40000 - 38400 = 1600
