Question

трое рабочих изготовили партию деталей.Первый и второй рабочие изготовили соответственно 30% и 40% всех деталей,а третий-на 8 деталей меньше,чем второй.Сколько всего деталей изготовили рабочие?

Answer 1

Вся партия деталей 100%,  30% + 40% = 70% изготовили первый и второй рабочие, тогда третий рабочий изготовил 100% - 70 % = 30%, он  изготовил на 8 деталей меньше или на 10% меньше чем второй. Т. е.
 8 деталей - 10%,
 х деталей - 100% 
х = 8*100% :10% = 80
Ответ: 80 деталей

Answer 2

Calculating the Total Number of Parts Produced by Workers

To calculate the total number of parts produced by the workers, we can use the information provided in the question and the search results.

First, let's break down the information given: - The first worker produced 30% of all the parts. - The second worker produced 40% of all the parts. - The third worker produced 8 parts less than the second worker.

Now, let's calculate the total number of parts produced by the workers.

Calculation

Let's assume the total number of parts produced is represented by P.

According to the information provided: - The first worker produced 30% of all the parts, which is 0.3P. - The second worker produced 40% of all the parts, which is 0.4P. - The third worker produced 8 parts less than the second worker, so the third worker produced 0.4P - 8 parts.

We can now set up an equation to find the total number of parts produced: 0.3P + 0.4P + (0.4P - 8) = P

Solving for P: 0.3P + 0.4P + 0.4P - 8 = P 1.1P - 8 = P -8 = P - 1.1P -8 = -0.1P P = -8 / -0.1 P = 80

Answer

The total number of parts produced by the workers is 80.
