Question

По норме рабочий должен изготовить 72 детали , а он изготовил 90 деталей . На сколько процентов рабочий выполнил норму и на сколько процентов он перевыполнил норму .

Answer 1

72 = 100% 

90 = x 

По свойству пропорции:

x = (90 * 100) / 72 =  125 %  - на столько выполнил норму.

 

125% - 100% = 25% - на столько перевыполнил норму.

Answer 2

Calculation of Percentage Completion

To calculate the percentage completion of the worker, we can use the following formula:

Percentage Completion = (Number of parts produced / Target number of parts) * 100

Given that the worker was supposed to produce 72 parts but actually produced 90 parts, we can calculate the percentage completion as follows:

Percentage Completion = (90 / 72) * 100 = 125%

Therefore, the worker has completed 125% of the target number of parts.

Calculation of Percentage Exceeded

To calculate the percentage by which the worker exceeded the target, we can use the following formula:

Percentage Exceeded = ((Number of parts produced - Target number of parts) / Target number of parts) * 100

Using the same values as before, we can calculate the percentage exceeded as follows:

Percentage Exceeded = ((90 - 72) / 72) * 100 = 25%

Therefore, the worker has exceeded the target by 25%.

Please note that these calculations assume that the target number of parts is fixed and does not take into account any specific requirements or constraints that may be in place for the production process.
