If you measure a pile of coal, you can transport 500 tons on the first day, which is exactly 1 / 4 of the pile of coal, and the ratio of the coal transported on the next day to the total quality of the pile of coal A pile of coal, 500 tons in the first day, just carried away 1 / 4 of this pile of coal, the next day and the total mass ratio of this pile of coal is 3:8, how many tons in the next day?

If you measure a pile of coal, you can transport 500 tons on the first day, which is exactly 1 / 4 of the pile of coal, and the ratio of the coal transported on the next day to the total quality of the pile of coal A pile of coal, 500 tons in the first day, just carried away 1 / 4 of this pile of coal, the next day and the total mass ratio of this pile of coal is 3:8, how many tons in the next day?

500/0.25 *3/8=750

For a pile of coal, 500 tons are transported in the first day, which accounts for 1 / 5 of this pile of coal. The ratio of coal transported in the second day to this pile of coal is 1:4. How many tons of coal are transported in the second day?

Because 500 tons of coal were transported on the first day, accounting for just 1 / 5 of the pile of coal,
So this pile of coal has: 500 divided by (1 / 5) = 2500 tons,
Because the ratio of the coal transported the next day to this pile of coal is 1:4,
So the coal transported the next day: 2500 divided by 4 = 625 tons
Its comprehensive formula is: 500 divided by (1 / 5) divided by 4 = 625 tons

Uncle Zhang transported a pile of coal. On the first day, he transported 1 / 4 more than 4 tons of the total. On the second day, he transported 3 tons more than 3 / 4 on the first day. On the third day, he transported 35 tons, which was just finished

Let Uncle Zhang transport this pile of coal as X tons [(1 / 4) x + 4] + {3 / 4 [(1 / 4) x + 4] + 3} + 35 = x (1 / 4) x + 4 + (3 / 16) x + 3 + 35 = x (7 / 16) x + 45 = x45 = x - (7 / 16) x45 = (9 / 16) XX = 80. This pile of coal is 80 tons. On the first day, it transported (1 / 4) x + 4 = (1 / 4) 80 + 4 = 24 tons. On the second day, it transported 3 / 4 [(1 / 4) x + 4] + 3 = 3

Uncle Zhang transported a pile of coal. On the first day, he transported 4 tons more than one fourth of the total tons. On the second day, he transported 3 tons more than three quarters of the total tons on the first day. On the third day, he transported 35 tons, which was just finished. How many tons of coal are there?

Suppose there are x tons in total
1/4X+4+3/4(1/4X+4)+3+35=X
The solution is x = 80
A total of 80 tons of coal
