Show answer & explanation
Correct answer: B
Add the demand values: 2000 + 300 + 1250 + 600 + 1650 = 5800. Average demand = 5800 / 5 = 1160. Add the production values: 1000 + 900 + 500 + 1350 + 1100 = 4850. Average production = 4850 / 5 = 970. Difference between the averages = 1160 - 970 = 190. Hence, option 2 is correct.
