The population of the country in 1990 is 249.5 million
Step-by-step explanation:
- Let 'x' be the population in 1990.
- The population in 2015 is 321.9 million.
The increase in x by 29% = 321.9[tex]\times[/tex]10^6
(since x is 100% and increase of 29% will be 129%)
129% of x = 321.9[tex]\times[/tex]10^6
1.29x = 321.9[tex]\times[/tex]10^6
x = 321.9[tex]\times[/tex]10^6/1.29
x = 249.5[tex]\times[/tex]10^6
x = 249.5 million.
∴ The population of the country in 1990 is 249.5 million
