Question

The population of a village is 80,000.It increases 5% by every year. find the population at the end of 2 years.

Answer 1

Answer:

The population after two years will be approximately 9159

Step-by-step explanation:

Present population = 80000

We are given that The population of a village increase by 7% every year

So, we are supposed to find he population after two years.

Time = 2 years

R = 7%

Formula : N(t)=N_0(1+r)^tN(t)=N

0

(1+r)

t

N(t)is the population after t years

N_0N

0

is the initial population

Substitute the values

N(t)=8000(1+0.07)^2N(t)=8000(1+0.07)

2

N(t)=9159.2N(t)=9159.2

Hence the population after two years will be approximately 9159

Answer 2

Answer:

the answer is 88,000

Step-by-step explanation:

The population of the village = 80,000

It increases by 5% every year,

Then the increase in population for 2 years =

2× 5/100 ×80,000 = 8,000

therefore, total population = 80,000 + 8,000 = 88,000
