Given : The population of a town increases 5% in the first year and 4% in the second year

the population was 250000 at the beginning of the first year

To Find : Population at the end of 2 years

Solution:

population  at the beginning of the first year  = 250000

The population of a town increases in the first year  = 5 %

= (5/100)250000

= 12500

Population at the end of 1st year / beginning of 2nd year = 250000 + 12500

= 262500

The population of a town increases in the 2nd  year  = 4 %

= (4/100) 262500

= 10500

Population at the end of  2nd year = 262500 + 10500

= 273000

To Find:

what is the population at the end of 2 years?

Solution:

It is given that the population of a town increases 5% in the first year.

=> 2,50,000 x 5/100

=> 12,500

=> 250000 + 12500

=> 262500

So, at the end of the first-year population is 262500

It is given that the population of a town increases 4% in the second year.

=> 262500 x 4/100

=> 10,500

=> 262500 + 10500

=> 273000

So, at the end of the second-year population is 273000
