Question

В первый день со склада вывези 40 процентов имевшегося там угля.Во второй день было вывезено 75 процентов остатка.Сколько процентов всего имевшегося на складе угля вывезли во второй день?Сколько процентов всего имевшегося там угля осталось?

Answer 1

весь уголь-100%

вывезли-40%

100-40=60% осталось

 

оставшийся (60%) уголь-100%

вывезли х%-75%

х=60*75:100=45% угля вывезли во второй день

 

60-45=15%  угля осталось

40%+45%+15%=100%

 

 

 

Answer 2

Calculation of Coal Removal from the Warehouse

To calculate the percentage of coal removed from the warehouse on the second day and the percentage of coal remaining, we need to follow the given information.

On the first day, 40% of the coal that was in the warehouse was removed. On the second day, 75% of the remaining coal was removed.

Let's calculate the percentages step by step:

1. Calculate the amount of coal removed on the first day: - 40% of the total coal was removed.

2. Calculate the remaining coal after the first day: - 100% - 40% = 60% of the total coal remained.

3. Calculate the amount of coal removed on the second day: - 75% of the remaining coal was removed.

4. Calculate the remaining coal after the second day: - 100% - 75% = 25% of the remaining coal remained.

Calculation Results

Based on the given information, we can conclude the following:

- Percentage of coal removed on the second day: 75% - Percentage of coal remaining after the second day: 25%

Please note that these calculations are based on the information provided and assume that no additional coal was added to or removed from the warehouse during this period.
