Question

В 2006 году в поселке Далекий Лес проживало 3000 человек. В 2007 году количество жителей снизилось на 12%, а в 2008 году - на 20% по сравнению с 2007 годом. Сколько человек стало проживать в поселке в 2008 году?

Answer 1

С помощью пропорции:
2006 год:     3000 - 100%
                      х    -  88% (100%-12%)    
х = 3000*88/100=2640
2007 год:      2640 - 100%
                       х    - 80% (100%-20%)
х=2640*80/100=2112

Ответ: В 2008 году в поселке стало проживать 2 112 человек

Calculation of Population in 2008

To calculate the population in the village of Distant Forest in 2008, we need to consider the population decrease in both 2007 and 2008.

In 2007, the population decreased by 12% compared to 2006 To calculate the population in 2007, we can use the following formula:

Population in 2007 = Population in 2006 - (12% of Population in 2006)

Let's calculate the population in 2007:

Population in 2007 = 3000 - (12/100 * 3000) = 3000 - 360 = 2640

So, the population in the village of Distant Forest in 2007 was 2640.

In 2008, the population decreased by 20% compared to 2007 To calculate the population in 2008, we can use the following formula:

Population in 2008 = Population in 2007 - (20% of Population in 2007)

Let's calculate the population in 2008:

Population in 2008 = 2640 - (20/100 * 2640) = 2640 - 528 = 2112

Therefore, the population in the village of Distant Forest in 2008 was 2112.
