The population bar graph of a country is given: What is the difference between the population in the years 2008 and 2007?

The correct option is (B),

To find the difference in the population between 2008 and 2007, we start by looking at the population bar graph for these two years. By carefully reading the values from the graph:

• The population in 2008 is 420 Lakhs.
• The population in 2007 is 370 Lakhs.

Now, subtract the population in 2007 from that in 2008:

Population difference = 420 Lakhs - 370 Lakhs
Population difference = 50 Lakhs
 

This means the population increased by 50 Lakhs from 2007 to 2008.
