Answer 3

Problem Analysis

We are given that 840 kg of potatoes were sold, and there are 240 kg more potatoes left to sell than what has already been sold. We need to determine the initial amount of potatoes.

Solution

Let's assume the initial amount of potatoes is x kg.

According to the given information, the amount of potatoes left to sell is 240 kg more than what has already been sold. So, the amount of potatoes left to sell is x + 240 kg.

We are also given that 840 kg of potatoes have already been sold. Therefore, the equation can be set up as follows:

x + 240 = 840

To find the initial amount of potatoes, we need to solve this equation for x.

Calculation

Let's solve the equation:

x + 240 = 840

Subtract 240 from both sides:

x = 840 - 240

x = 600

Answer

The initial amount of potatoes was 600 kg.
