What is the difference between average demand and average production of the five companies taken together?

• A. 1400
• B. 400
• C. 280
• D. 138

Answer 1

The correct option is C 280

Average demand

$=\left(\frac{3000+600+2500+1200+3300}{5}\right)$

$=2120$

Average production

$=\left(\frac{1500+1800+100+2700+2200}{5}\right)$

$=1840$

$\therefore$ Difference in having average demand & production = (2120 - 1840)
= 280
