The total weight of the three piles of coal is 30 tons. If one ton is transported from the first pile and the second pile to the third pile respectively, the mass ratio of the three piles of coal is 2:1 It's urgent. It's better to solve it today
∵ the final mass ratio of three piles of coal is 2:1:2
The quality of the three piles of coal is 30 / (2 + 1 + 2) * 2 = 12 for the first team, 30 / (2 + 1 + 2) = 6 for the second pile, and 30 / (2 + 1 + 2) * 2 = 12 for the third pile
The original mass is the first pile: 12 + 1 = 13, 2: 6 + 1 = 7, 3: 12-2 = 10
The unit itself adds --
Three piles of 30 tons of coal. If one ton is transported from the first pile and the second pile to the third pile, the weight ratio of the three piles is 2:1:3. How many tons are there in the three piles?
2: At 1:3, the first is 10 tons, the second is 5 tons, and the third is 15 tons. When pushed back, the first pile is 11, the second pile is 6, and the third pile is 13,
