Question

После того как токарь выполнил 75 % всей работы, он посчитал, что оставшуюсяработу сделает за 50 минут. сколько времени необходимо для выполнения всей работы?

Answer 1

100-75=25 процентов работы он сделает за 50 минут, значит составим пропорцию. 25 это 50минут, а 100 это Х. 25х=5000 Отсюда Х=200 минут

Answer 2

Time Required to Complete the Remaining Work

If the worker believes that the remaining work can be completed in 50 minutes after finishing 75% of the total work, we can calculate the time required to complete the entire task.

Let's denote the total time required to complete the work as T and the time taken to complete 75% of the work as 75% of T.

The time taken to complete 75% of the work is 75% of the total time, which can be expressed as: 75% of T = 0.75T

The remaining work is 25% of the total work, and the worker believes it can be completed in 50 minutes. Therefore, we can express this as: 25% of T = 50 minutes

To find the total time required to complete the entire work, we can use the following equation: 75% of T + 25% of T = T

Solving for T: 0.75T + 0.25T = T 1T = T

This means that the total time required to complete the entire work is equal to the time required to complete the remaining 25% of the work, which the worker believes is 50 minutes.

So, the time required to complete the entire work is 50 minutes.
