In 1st year

The no.of births = 8.5*125000/100 = 10625

The no.of deaths = 3.5*125000/100 = 4375

Therefore the total population after 1 year = 125000+10625-4375 = 131250

In 2nd year

The no.of births = 8.5*125000/100 = 10625

The no.of deaths = 3.5*125000/100 = 4375

Therefore the total population after 2 years = 131250+10625-4375 = 137500

In 3rd year

The no.of births = 8.5*125000/100 = 10625

The no.of deaths = 3.5*125000/100 = 4375

Therefore the total population after 3 years = 137500+10625-4375 = 143750.

The population of city after 3 years = 143750

First Year:--

The no.of births = 8.5*125000/100

= 10625

The no.of Deaths = 3.5*125000/100

= 4375

Therefore the total population after 1 year = 125000+10625 - 4375 = 131250

Second year

Initial Population = 131250

The no.of births = 8.5*131250/100

=11156.25

= 11156

The no.of deaths = 3.5*131250/100

= 4593.75

= 4393

Therefore the total population after 2 years = 131250+ 11156 - 4393 = 138013

Third Year

The no.of births = 8.5*

= 11731.105

=

The no.of deaths = 3.5*

= 4830. 455

=

hence polpulation of city after 3 year = 144914

Hope this helps you!!!
