Answer 3

Problem Analysis

We are given that a total of 1400 kg of vegetables were sold over three days. On the first day, 170 kg more vegetables were sold than on the second day, and on the third day, 120 kg fewer vegetables were sold than on the second day. We need to find out how many kilograms of vegetables were sold on the second day.

Solution

Let's assume that the number of kilograms of vegetables sold on the second day is x kg.

According to the given information: - On the first day, 170 kg more vegetables were sold than on the second day, so the number of kilograms sold on the first day is x + 170 kg. - On the third day, 120 kg fewer vegetables were sold than on the second day, so the number of kilograms sold on the third day is x - 120 kg.

The total number of kilograms sold over the three days is 1400 kg. Therefore, we can write the equation:

x + (x + 170) + (x - 120) = 1400

Simplifying the equation: 3x + 50 = 1400

Subtracting 50 from both sides: 3x = 1350

Dividing both sides by 3: x = 450

Therefore, 450 kg of vegetables were sold on the second day.

Answer

450 kilograms of vegetables were sold on the second day.
