Известно, что за 2011 год численность населения страны Z снизилась на 2%, численность экономически активного населения увеличилась на 25%, а количество безработных снизилось на 10%. Сколько процентов в конце 2011 года составил уровень безработицы в стране Z?

Answer 1

В начале 2011 года уровень
безработицы в стране Z был равен 25%.
Известно, что за 2011 год численность
населения страны Z снизилась на 2%,
численность экономически активного
населения увеличилась на 25%, а
количество безработных снизилось на 10%.
Тогда уровень безработицы в стране Z
в конце 2011 года составил:18%

Answer 2

Calculation of Unemployment Rate in Country Z

To calculate the unemployment rate at the end of 2011 in country Z, we need to consider the given information:

- At the beginning of 2011, the unemployment rate in country Z was 25%. - The population of country Z decreased by 2% during 2011. - The number of economically active people increased by 25% during 2011. - The number of unemployed people decreased by 10% during 2011.

To calculate the unemployment rate at the end of 2011, we need to determine the number of unemployed people and the total labor force.

Calculation of the Number of Unemployed People

Let's assume the initial population of country Z at the beginning of 2011 is 100.

- The population decreased by 2%, so the population at the end of 2011 is 100 - (2% of 100) = 98. - The number of economically active people increased by 25%, so the number of economically active people at the end of 2011 is 100 + (25% of 100) = 125. - The number of unemployed people decreased by 10%, so the number of unemployed people at the end of 2011 is 25 - (10% of 25) = 22.5.

Since the number of unemployed people cannot be a fraction, we round it to the nearest whole number. Therefore, the number of unemployed people at the end of 2011 is 23.

Calculation of the Unemployment Rate

The unemployment rate is calculated by dividing the number of unemployed people by the total labor force and multiplying by 100.

- The number of unemployed people at the end of 2011 is 23. - The total labor force at the end of 2011 is 125.

The unemployment rate at the end of 2011 in country Z is (23 / 125) * 100 = 18.4%.

Therefore, the unemployment rate in country Z at the end of 2011 was approximately 18.4%.
