Answer:
population will be 79806.
Step-by-step explanation:
Population of a town 4 years ago was 50,000
Population of town had grown exponentially and present population is 63,124.

Where
= Final population n = number of years.
= Initial population
r = rate of increase in population per year.
so 63124 = 50,000 


= 1.0813
Now we have to find the population after 4 years from now.
= 
= 
= 63124 × 1.264
= 79806
Therefore, after 4 years from now population will be 79806.
