The volume of the first container is 30 liters more than the volume of the second container.

The volume of the first container is 30 liters more than the volume of the second container. 2/5 of the volume of the first container is equal to 1/2 of the volume of the second container. Find the volume of the containers.

Suppose the volume of the second container is x liters.

Since the volume of the first is 30 liters larger, it is: x + 30 liters.

We draw up an equality in which 2/5 of the volume of the first container is equal to 1/2 of the volume of the second container.

Will be:

2/5 * (x + 30) = 1/2 * x.

2/5 * x + 12 = 1/2 * x.

12 = 1/2 * x – 2/5 * x.

12 = 1/10 * x.

x = 12 / 1/10 = 12 * 10 = 120 liters (in the first container).

x + 30 = 120 + 30 = 150 liters in the second container.

We check:

1/2 * 120 = 120/2 = 60 liters.

2/5 * 150 = 300/5 = 60 liters.

Answer:

150 and 120 liters.
