Question

1.  ДАМ 15 БАЛЛОВ    Рабочий на заводе выточил некоторое количество деталей за 4 смены. При этом известно, что в первую смену он выточил  половину деталей от количества деталей сделанных во вторую смену. В третью смену было изготовлено 10% всех деталей, а во вторую 50%. Сколько всего изготовил рабочий за 4 смены, если известно, что в первую смену он выточил 125 деталей. Сколько деталей изготовлено в 4 смену? ​

Answer 1

Ответ:

500 деталей за 4 смену; 75 деталей за четвертую смену

Пошаговое объяснение:

10%=0,1

50%=0,5

1) 125*2=250 шт. - вторая смена

2) 250/0,5=500 шт. - за 4 смены

3) 125+250=375 шт. - первая и вторая смена

4) 500*0,1=50 шт. - третья смена

5) 375+50=425 шт. - первая, вторая и третья смена

6) 500-425=75 шт. - четвертая смена

Answer 2

To solve this problem, we need to determine the total number of parts produced by the worker in four shifts. We are given the following information:

- In the first shift, the worker produced half of the parts made in the second shift. - In the third shift, 10% of all the parts were produced. - In the second shift, 50% of all the parts were produced. - In the first shift, the worker produced 125 parts.

Let's break down the problem step by step:

Step 1: Determine the number of parts produced in the second shift

We are told that the worker produced half of the parts made in the second shift. Since we know the number of parts produced in the first shift (125), we can calculate the number of parts produced in the second shift by doubling that number.

Number of parts produced in the second shift = 2 * 125 = 250

Step 2: Determine the number of parts produced in the third shift

We are told that 10% of all the parts were produced in the third shift. To find the number of parts produced in the third shift, we need to calculate 10% of the total number of parts produced in the first and second shifts.

Number of parts produced in the third shift = 10% of (125 + 250) = 10% of 375 = 0.1 * 375 = 37.5

Since we cannot have a fraction of a part, we round this number to the nearest whole number.

Number of parts produced in the third shift = 38

Step 3: Determine the number of parts produced in the fourth shift

We are not given any specific information about the number of parts produced in the fourth shift. However, we know that the total number of parts produced in four shifts is the sum of the parts produced in each individual shift.

Number of parts produced in the fourth shift = Total number of parts produced - (Number of parts produced in the first shift + Number of parts produced in the second shift + Number of parts produced in the third shift)

Let's calculate the total number of parts produced first.

Total number of parts produced = Number of parts produced in the first shift + Number of parts produced in the second shift + Number of parts produced in the third shift

Total number of parts produced = 125 + 250 + 38 = 413

Now, we can calculate the number of parts produced in the fourth shift.

Number of parts produced in the fourth shift = 413 - (125 + 250 + 38) = 413 - 413 = 0

Based on the given information, it seems that the worker did not produce any parts in the fourth shift.

Therefore, the worker produced a total of 413 parts in four shifts, with 0 parts produced in the fourth shift.
