Question

Решите брига Бригада рабочих за 1 день сделать 25% От запланированного количества деталей а во второй день 40% от оставшегося количества Определите Сколько деталей запланировала сделать бригады рабочих если во второй день они сделали 120 деталей

Answer 1

Составим пропорцию.Обозначим оставшиеся детали х
х  -    100 %
120  - 40 %        х = 120 *100 \ 40 = 300 деталей оставалось на второй день
100 - 25 = 75 % составляют  300 деталей

х - 100%
300 - 75 %       х = 400 деталей запланировала бригада

Answer 2

Problem Analysis

We are given the following information: - On the first day, a team of workers completed 25% of the planned quantity of parts. - On the second day, they completed 40% of the remaining quantity of parts. - We are also given that on the second day, they completed 120 parts.

We need to determine the total number of parts that the team of workers planned to complete.

Solution

Let's assume that the planned quantity of parts is represented by x.

On the first day, the team completed 25% of the planned quantity, which is equal to 0.25x.

On the second day, they completed 40% of the remaining quantity. The remaining quantity can be calculated by subtracting the parts completed on the first day from the planned quantity: x - 0.25x = 0.75x. Therefore, on the second day, they completed 0.4 * 0.75x = 0.3x parts.

We are given that on the second day, they completed 120 parts. So we can set up the equation:

0.3x = 120

To solve for x, we divide both sides of the equation by 0.3:

x = 120 / 0.3 = 400

Therefore, the team of workers planned to complete 400 parts.

Answer

The team of workers planned to complete 400 parts.
