Problem Analysis

We are given that a store sold 1240.8 kg of sugar over a period of 3 days. On the first day, 543 kg of sugar was sold. On the second day, the amount sold was three times the amount sold on the third day. We need to find out how much sugar was sold on the third day.

Solution

Let's solve this problem step by step.

1. On the first day, 543 kg of sugar was sold. 2. On the second day, the amount sold was three times the amount sold on the third day. 3. Let's assume the amount of sugar sold on the third day is x kg.

According to the given information, we can set up the following equation:

543 + 3x + x = 1240.8

Simplifying the equation:

4x = 1240.8 - 543 4x = 697.8 x = 697.8 / 4 x = 174.45

Therefore, 174.45 kg of sugar was sold on the third day.

Answer: 174.45 kg
