Question
Study the bar graph given below and answer the questions that follow.

$a.$ What information does the above bar graph represent?
$b.$ In which year was production the least?
$c.$ After which year was the maximum rise in the production?
$d.$ Find the average production of rice during the $5$ years.
$e.$ Find difference of rice production between years $2006$ and $2008.$
✓

Answer

After studying the bar graph, we have
Production of rice in $2005 = 50$ million tonne
Production of rice in $2006 = 40$ million tonne
Production of rice in $2007 = 70$ million tonne
Production of rice in $2008 = 50$ million tonne
Production of rice in $2009 = 60$ million tonne
$a.$ The bar graph shows the production of rice in million tonne by a country during years $2005$ to $2009.$
$b.$ The production of rice was the least in $2006,  i.e. 40$ million tonne.
$c.$ The maximum production of rice was in $2007$. The production rose after $2006.$
$d.$ For average production,
Sum of productions $= 50 + 40 + 70 + 50 + 60 = 270$
Average production $=\frac{\text{Sum of observations}}{\text{Number of observations}}$
Average production $=\frac{270}{5}=54$ million tonne
$e.$ Production in $2006 = 40$ million tonne and production in $2008 = 50$ million tonne
Difference $= 50 - 40 = 10$ million tonne.
