Question

the present population of a village is 25000 if the population growth rate of the village is 2% per annum what will be the population after 2 years

Answer 1

Answer:

34155

Step-by-step explanation:

Population 3 years ago = 25000

Population increased at the rate of 10%, 15%, 8%

Now, after an increase in 10% of population,

New population = 25000 + 10% of 25000 = 25000+

100

10

×25000=27500

After an increase in 15% of the population,

New population= 27500 + 15% of 27500 = 27500+

100

15

×27500=31625

After an increase in 8% of the population,

New population = 31625 + 8% of 31625 = 31625+

100

8

×31625=34155

Hence, the present population is 34155

Answer 2

Answer:

Given details are,

Present population of town is = 28000

Rate of increase in population is = 5% per annum

Number of years = 2

By using the formula,

A = P (1 + R/100)n

Population of town after 2 years = 28000 (1 + 5/100)2

= 28000 (1.05)2

= 30870

∴ Population of town after 2 years will be 30870
