Question

The present population of a town is 15,000. If the population increases at the rate of

4% per year, then find the population after one year​

Answer 1

Answer:

15600

Step-by-step explanation:

after one year=104/100×15000=15600

Answer 2

Given:

A town with

• Population = 1500
• Rate = 4%
• Time = 1 year

What To Find:

We have to find the population of the town after one year.

How To Find:

To find the population of the town, we have to

• Use the formula.
• Substitute the value.
• Solve to find the population.

Formula:

$\sf Total \: Population = Present \: Population \bigg(1 + \dfrac{R}{100} \bigg) ^T$

Solution:

Using the formula,

$\sf \Rightarrow Total \: Population = Present \: Population \bigg(1 + \dfrac{R}{100} \bigg) ^T$

Substitute the values,

$\sf \Rightarrow Total \: Population = 15000 \bigg(1 + \dfrac{4}{100} \bigg) ^1$

Solve the brackets,

$\sf \Rightarrow Total \: Population = 15000 \times \dfrac{104}{100}$

Cancel the zeros,

$\sf \Rightarrow Total \: Population = 150 \times 104$

Multiply 150 by 104,

$\sf \Rightarrow Total \: Population = 15600$

∴ Thus, the present population of a town is 15600.
