During the first year second year and the third year the population increase at a rate of 5%, 6% and 8% respectively

To find: present population of the village

The present population is given by formula:

Where,

p = initial population

x = rate of increase at first year

y = rate of increase at second year

z = rate of increase at third year

Here given that,

x = 5 %

y = 6 %

z = 8 %

p = 25000

Substituting the values we get,

Thus present population of the village is 30051
