Initially the population of the city is 125000
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

Population Of City = 125000
               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
   Initial Population = 138013
The no.of births = 8.5*
138013/100
                       = 11731.105
                       =11731
                                            
The no.of deaths = 3.5*
138013/100
                         = 4830. 455
                         =4830
Therefore the total population after 3 years =
138013+11731 - 4830  = 144914

 hence polpulation of city after 3 year = 144914

Hope this helps you!!!
