Calculating the Total Potato Harvest by Three Classes

To calculate the total potato harvest by three classes, we can use the given information and solve for the total amount of potatoes harvested.

Let's denote: - The amount of potatoes harvested by the first class as x kg. - The amount of potatoes harvested by the second class as x + 20 kg (20 kg more than the first class). - The amount of potatoes harvested by the third class as x + 40 kg more than the combined harvest of the first and second classes.

Calculations

1. The first class harvested 230 kg of potatoes. 2. The second class harvested 20 kg more than the first class, so they harvested 230 + 20 = 250 kg of potatoes. 3. The combined harvest of the first and second classes is 230 + 250 = 480 kg. 4. The third class harvested 40 kg more than the combined harvest of the first and second classes, so they harvested 480 + 40 = 520 kg of potatoes.

Therefore, the total amount of potatoes harvested by the three classes is 520 kg.

This calculation is based on the given information and the relationships between the amounts harvested by each class.
