Problem Analysis

To solve this problem, we need to determine the amount of flour sold after lunch. We know that 600 kg of flour was sold during the day, and after lunch, the amount of flour sold was twice the amount sold before lunch.

Solution

Let's denote the amount of flour sold before lunch as x kg. According to the problem, the amount of flour sold after lunch is twice the amount sold before lunch. Therefore, the amount of flour sold after lunch is 2x kg.

We also know that the total amount of flour sold during the day is 600 kg. So we can write the equation:

x + 2x = 600

Simplifying the equation, we get:

3x = 600

To find the value of x, we divide both sides of the equation by 3:

x = 600 / 3 = 200

Therefore, the amount of flour sold before lunch is 200 kg, and the amount of flour sold after lunch is twice that amount, which is:

2x = 2 * 200 = 400 kg

So, after lunch, 400 kg of flour was sold.

Answer

After lunch, 400 kg of flour was sold.
