The population bar graph of a country is given:

In which year are the population maximum and minimum, and what is the difference between the maximum and minimum?

 

The correct option is (C),

The population of the country can be found by looking at the value of the bar where the x-axis denotes the year and the y-axis represents the population in lakhs.

The population is maximum in the year $2008$.

The population of the country in the year $2008$ is $400$ Lakhs.

The population is minimum in the year $2005$.

The population of the country in the year $2005$ is $150$ Lakhs

Hence, the difference in the maximum and minimum population is $400-150=250$ Lakhs.
