Question

the present population of a town is 50,000. If it is expected to grow at 4% 5% and 8% during the first second and third year respectively find the expected population after 3 years​

Answer 1

Answer:57813

Step-by-step explanation:

At the end of 1st year, total population will be

50000+3% of 50000

=50000+(3/100)×50000

=50000+3×500=50000+1500=51500

At the end of 2nd year it will be

51500+4%of 51500

=51500+(4/100)×51500

=51500+4×515=51500+2030=53530

At end of 3rd year it will be

53530+8% of 53530

=53530+(8/100)×53530

=53530+4282.4=57812.4

=57813 approximately
