Answer 2

Solution:

Let's break down the problem step by step.

1. Total Sugar Sold in 3 Days: - The store sold a total of 1240.8 kg of sugar in 3 days.

2. Sugar Sold on the First Day: - On the first day, the store sold 543 kg of sugar.

3. Sugar Sold on the Second Day: - The sugar sold on the second day was twice the amount sold on the third day.

4. Sugar Sold on the Third Day: - We need to find out how much sugar was sold on the third day.

Calculation:

Let's calculate the amount of sugar sold on the second and third days.

1. Sugar Sold on the Second Day: - If the sugar sold on the third day is represented as 'x' kg, then the sugar sold on the second day is '2x' kg.

2. Total Sugar Sold: - The total sugar sold in 3 days is 1240.8 kg.

3. Equation: - We can set up the equation: 543 + 2x + x = 1240.8

4. Solve for x: - Solving the equation will give us the amount of sugar sold on the third day.

Answer:

The amount of sugar sold on the third day is 154.8 kg.

This is calculated by solving the equation: 543 + 2x + x = 1240.8, where x represents the amount of sugar sold on the third day.
