The population bar graph of a country is given:

What is the difference between the population in the years $2006$ and $2005$?

The correct option is (D),

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

The population of the country in the year $2006$ is $220$ Lakhs.

Hence, the difference between the population in the years $2006$ and $2005$ is $220-150=70$ Lakhs.
