There are two granaries A and B. It is known that the grain stored in a granary is three times as much as that in B granary. Now the grain stored in a granary is increased by 80t and that in B granary is increased by 100t. At this time, the grain stored in a granary is twice as much as that in B granary How many tons of grain were stored in warehouse B?
If warehouse B is set to store x tons of grain, warehouse a will store 3x tons of grain
Now there are 3x + 80 tons of grain in warehouse A and X + 100 tons in warehouse B,
The countable equation is 3x + 80 = 2 (x + 100),
The solution is: x = 120,
That is: B warehouse original storage 120 tons of grain
There are 100 tons of grain in warehouse A and 80 tons in warehouse B. how many tons of grain are taken from warehouse A and distributed to warehouse B? The ratio of grain in warehouse A and warehouse B is 7:11?
7 + 11 = 18100 - (100 + 80) × 718 = 100-180 × 718 = 100-70 = 30 tons. A: after 30 tons are taken from warehouse A and distributed to warehouse B, the ratio of grain in warehouse A and warehouse B is 7:11
For a pile of coal, 20% of the total amount was transported in the first day, and 7 / 15 of the total amount was transported in the second day. The first day transported 80 tons less than the second day. How many tons of this pile of coal?
I'm going to trouble you again,
The total weight is x tons
20% x + 7x of 15 + 7x of 15-80 = x
------2X / 3 + 7x-80 / 15 = x
-----------------2X out of 15 = x
------------------------X=600
Remove the "-"
I'll find you later. I'm a master!
I'm right
You can test it
A certain factory transported a batch of coal. On the first day, it transported 1 / 3 of the total amount and 35 tons more. On the second day, it transported 3 / 5 of the first day. It was finished in two days. How much is this batch of coal
I don't want x, Y!
On the first day, one third of the total amount was transported, 35 tons more,
On the second day, it transported 3 / 5 of the first day, that is to say, on the second day, it transported 1 / 3 × 3 / 5 = 1 / 5 of the total, and 35 × 3 / 5 = 21 tons more
(35 + 21) / (1-1 / 3-1 / 5) = 120 (tons)
