Problem Analysis

We are given that 120 kg of sugar was sold over three days in a store. On the first day, 5 kg of sugar was sold. On the second day, 50% of the sugar sold on the first day was sold. And on the third day, the remaining sugar was sold. We need to determine how much sugar was sold on the third day.

Solution

To find the amount of sugar sold on the third day, we need to calculate the remaining sugar after the second day and subtract it from the total amount of sugar sold.

Let's break down the solution step by step:

1. Calculate the amount of sugar sold on the second day: - We are given that 50% of the sugar sold on the first day was sold on the second day. - The amount of sugar sold on the first day is 5 kg. - Therefore, the amount of sugar sold on the second day is 50% of 5 kg, which is 2.5 kg.

2. Calculate the remaining sugar after the second day: - We know that the total amount of sugar sold over three days is 120 kg. - The amount of sugar sold on the first day is 5 kg, and the amount sold on the second day is 2.5 kg. - Therefore, the remaining sugar after the second day is 120 kg - 5 kg - 2.5 kg = 112.5 kg.

3. Calculate the amount of sugar sold on the third day: - The amount of sugar sold on the third day is equal to the remaining sugar after the second day, which is 112.5 kg.

Answer

Therefore, the amount of sugar sold on the third day is 112.5 kg.
