The rate at which the population of a city increases at any time is propotional to the population at that time. If there were 1,30,000 people in the city in 1960 and 1,60,000 in 1990 what population may be anticipated in 2020.[loge(16/13)=.2070;e.42=1.52]

Find the population of a city at any time t, given that the rate of increase of population is proportional to the population at that instant and that in a period of 40 years the population increased from 3,00,000 to 4,00,000.

The population of a village increases continuously at the rate proportional to the number of its Inhabitants present at any time. It the population of the village was 20,000 in 1999 and 25,000 in the year 2004, what will be the population of the village in 2009 ?

Population of a city in the years 2005 and 2010 are 1,35,000 and 1,45,000 respectively. Find the approximate population in the year 2015. (assuming that the growth of population is constant)

In a newly developed city, it is estimated that the voting population (in thousands) will increase according to V(t) = 30 + 12t^(2)-t^(3), 0 le t le 8 where t is the time in years. Find the approximate change in voters for the time change from 4 to 4(1/6) year.
