Solution
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 = `"Sum of observations"/"Number of observations"`
Average production = `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.
