Question

The total population of village increased from 18,000 to 22,500 in a decade.the average percentage increase of population per year of that village is

Answer 1

Answer:

Step-by-step explanation:

Population earlier ( 10 years ago ) = 18000.

Population at present of the village = 22500.

So population increases by 22500-18000 = 4500 in 10 years.

So per year 450 people take birth every year.

So population increased by 4500 in 10 years.

So formula for increment percentage= population increasesd (per annum ) / population earlier ×100

=450/18000 ×100

=1/40 × 100

=100/40

=5/2 % or 2.5% increase.
