Find the population of city at any time t given that rate of increase of population is proportional to the population at that instant & that period of 40 years the population increased from 30000 to 40000.

The population of a city increase at a rate proportional to the population at that time. In 40 years the population is increased from 30,000 to 40,000 then after time t, the population is

The population of a city increases at a rate proportional to the population at that time. If constant of proportionality is 0.04, then population of a city after 25 years, when initial polulation is 10,000 is (e=2.72)

These is increase in population in cities due to

The population of a city at present is 80000. If it increase by 5% per year, what will be the population after 3 years?

The population of a city increases by 30% every year. If the present population is 338000, then what was the population of the city of two years ago ?

The population of a city was 20,000 in the year 1997. It increased at the rate of 5% p.a.Find the population at the end of the year 2000.

The population of a city is 250000.It is increasing at the rate of 2% every year.The growth in the population after 2 yr is?

The polulation of a city increases at a rate propotional to the population at that time. If the population of the city is doubled in 60 years, then population will be triplet in (log2=0.6912,log 3=1.0986)

The population of city doubles in 80 years , in how many year will it be triple when the rate of increase is proportional to the number of inhabitants.
