Question

На заводе 80% рабочих стали перевыполнять план на 12%. На сколько процентов увеличилась на заводе производительность?

Answer 1

Если бы на заводе все 100% стали перевыполнять план на 12%, то производительность выросла бы на 12%

Но у нас только 80% таких рабочих, значит 0,8*0,12=0,096 или 9,6%

Ответ 9,6%

Answer 2

Calculation of Increased Productivity

To calculate the percentage increase in productivity at the factory, we need to determine the difference between the actual output and the planned output, and then express that difference as a percentage of the planned output.

Given that 80% of the workers at the factory are exceeding the plan by 12%, we can assume that the remaining 20% of workers are meeting the plan.

Let's assume that the planned output is represented by 100 units.

- 80% of the workers are exceeding the plan by 12%, which means they are producing an additional 12 units each. - The remaining 20% of workers are meeting the plan, so they are producing the planned 100 units.

To calculate the total output, we can sum the output of the two groups:

- 80% of workers: 80% * 12 units = 9.6 units - 20% of workers: 20% * 100 units = 20 units

The total output is 9.6 units + 20 units = 29.6 units.

To calculate the percentage increase in productivity, we can compare the total output to the planned output:

- Percentage increase = (Total output - Planned output) / Planned output * 100 - Percentage increase = (29.6 units - 100 units) / 100 units * 100 - Percentage increase = -70.4 units / 100 units * 100 - Percentage increase = -70.4%

Therefore, the productivity at the factory has decreased by 70.4%.

Please note that the calculation assumes that the planned output is 100 units and that the workers' performance is consistent across all units produced. The actual values may vary based on the specific circumstances of the factory.
