Question

The population of the Sims Alpha is 10,000,000 of inhabitants and increases of 500,000 a year. Sims Beta is 5,000,000 inhabitants, and it increases by 3% annually. Write a java program to determine how many years the population of Sims Beta will exceed that of the Sims Alpha

Answer 1

increase in population over last 8 decades is 7500 and average incremental increase during 8 decades is 750. The population of the city based on incremental method, in the year 2020 will be

[A]. 55,000

[B]. 60,500

[C].

66,500

[D]. 72,500

[E]. 76,500

By incremental increase method, Pn = P + n (Average Increase+ Incremental Increase)

Given: P=50,000 ; n=2 ; Average Increase = 7500 ; Incremental Increase = 750,

Hence P2=50000+2(7500+750) = 66,500.
