Calculation of Water Flow in the River

To calculate the amount of water that flows through point B in the river, we need to follow the given information about the river's flow and the division of its channels.

1. The river starts at point A and carries 12,000 liters of water at that point. 2. The river's channel divides into two at point B. 3. The left channel allows 1/3 of the water to flow through. 4. The right channel carries the remaining water.

After the division at point B, the right channel further divides into two at point C.

5. The left channel of the right branch carries 3/4 of the water. 6. The right channel of the right branch carries the remaining water.

Now, let's calculate the amount of water that flows through point B.

1. At point B, the left channel carries 1/3 of the water from point A, which is (1/3) * 12,000 liters = 4,000 liters. 2. The right channel carries the remaining water, which is 12,000 liters - 4,000 liters = 8,000 liters.

Next, let's calculate the amount of water that flows through point C.

1. The left channel of the right branch carries 3/4 of the water from point B, which is (3/4) * 8,000 liters = 6,000 liters. 2. The right channel of the right branch carries the remaining water, which is 8,000 liters - 6,000 liters = 2,000 liters.

Therefore, at point C, the left channel carries 6,000 liters of water.

To summarize:

- At point B, the left channel carries 4,000 liters of water. - At point C, the left channel carries 6,000 liters of water.
