Question

Фирма за 30 дней должна была сшить 2400 пиджаков. На выполнение заказа были взяты доплнительные люди, поэтому в день шили на 20 пиджаков больше,чем планировали.На сколько дней раньше срока был выполнен этот заказ?

Answer 1

2400:30=80(кост.)должны были шить в день
80+20=100(кост.)шили в день
2400:100=24(дн.)шили дней
30-24=6(дн.)
ответ:на 6 дней раньше был выполнен заказ.
(мне кажется как-то так?!)

Answer 2

Calculation of the Order Completion Time

To determine how many days earlier the order was completed, we need to calculate the number of jackets produced per day and compare it to the expected production rate.

Given: - The company had to sew 2400 jackets in 30 days. - Additional workers were hired, resulting in 20 jackets being sewn per day more than planned.

To calculate the number of jackets produced per day, we can subtract the additional jackets from the total jackets and divide by the number of days: ``` Jackets produced per day = (Total jackets - Additional jackets) / Number of days ```

Let's calculate the number of jackets produced per day: ``` Total jackets = 2400 Additional jackets per day = 20 Number of days = 30

Jackets produced per day = (2400 - (20 * 30)) / 30 = (2400 - 600) / 30 = 1800 / 30 = 60 ```

Therefore, the company produced 60 jackets per day.

Calculation of the Early Completion Time

To calculate how many days earlier the order was completed, we need to find the difference between the actual number of days taken to complete the order and the planned number of days.

Let's calculate the early completion time: ``` Actual number of days taken = 30 Planned number of days = 2400 / 60 = 40

Early completion time = Planned number of days - Actual number of days taken = 40 - 30 = 10 ```

Therefore, the order was completed 10 days earlier than planned.
