Question

The given bar graph shows the demand and production of colour T.Vs of five companies.
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 of companies
$=$ $\frac{1}{5}$ $(3000+600+2500+1200+3300)=2120$
Average production of companies
$=$ $\frac{1}{5}$ $(1500+1800+1000+2700+2200)$
$=$ $\frac{9200}{5}$ $=1840$
Therefore, required difference $=2120-1840=280$.
