A fleet transports a pile of coal. On the first day, it transports 1 / 6 of the pile of coal. On the second day, it transports 40 tons more than on the first day. At this time, the ratio between the transported coal and the remaining tons of coal is 7:5. How many tons are there in this pile of coal?
At this time, the ratio of the transported coal to the remaining tons of coal is 7:5,
Then, a total of 7 / (7 + 5) = 7 / 12 of the coal will be transported in two days;
It is known that one sixth of the coal was transported on the first day,
It can be concluded that 7 / 12-1 / 6 of the coal transported the next day is 5 / 12;
Because the next day, 40 tons more coal was transported than 1 / 6 of the pile,
Therefore, this pile of coal has a total of 40 (5 / 12-1 / 6) = 160 tons



A fleet transports a pile of coal. On the first day, it transports 16 tons of this pile of coal. On the second day, it transports 30 tons more than the first day. At this time, the ratio of the transported coal to the remaining tons is 7:5. How many tons are there in this pile of coal?





A fleet transports a pile of coal. On the first day, it transports 1 / 5 of the pile of coal. On the second day, it transports 30 tons more than on the first day
The ratio of the remaining tons of coal is 7:5. How many tons of coal are there?


Let this coal be X:
The rest is X - (1 / 5 * x + 1 / 5 * x + 30)
1 / 5 * x + 1 / 5 * x + 30
Two forms / one form = 7 / 5
The best x is 32.7273
About 33 tons
The above is for reference only, thank you!



When a fleet transports a pile of coal, it transports 1 / 6 of the pile of coal on the first day, and 30 tons more on the second day than on the first day. At this time, the ratio of the transported coal to the remaining coal tons is 7:5, which is a big problem
How many tons of coal is there in this pile


How much is this ton of coal?
A total of X tons of coal
The first day is x / 6, the second day is x / 6 + 30,
A total of X / 3 + 30, then the rest is x-x / 3-30 = 2x / 3-30
So x / 3 + 30:2x / 3-30 = 7:5
So x = 120
So this ton of coal has 120 tons in total, 20 tons are transported the first day, 50 tons are transported the next day, and 50 tons are left
I hope it will help you
