Answer:
[tex]15.22\%[/tex]
Step-by-step explanation:
The population in 1981 is 46 million.
In 2011, the population increased to 53 million.
The increase in population is (53 -46)million =7 million
Now we express 7 million as a percentage of 46 million
[tex]=\frac{7}{46}*100\%[/tex]
[tex]=0.1522*100\%[/tex]
=15.22%
