Answer 2

To solve this problem, we can break it down into steps:

1. Calculate the total amount of sugar bought on the second day. 2. Calculate the amount of sugar sold on the second day. 3. Calculate the amount of sugar bought on the third day. 4. Subtract the amount of sugar sold on the second day and the amount of sugar bought on the third day from the initial amount of sugar to find the remaining amount.

Let's go through each step:

1. Calculate the total amount of sugar bought on the second day: - On the first day, 87 kg of sugar was bought. - On the second day, 21 kg more than the first day was bought. - So, on the second day, 87 kg + 21 kg = 108 kg of sugar was bought.

2. Calculate the amount of sugar sold on the second day: - On the second day, half of the sugar bought on the first day was sold. - Half of 87 kg is 87 kg / 2 = 43.5 kg of sugar sold on the second day.

3. Calculate the amount of sugar bought on the third day: - On the third day, half of the sugar sold on the second day was bought. - Half of 43.5 kg is 43.5 kg / 2 = 21.75 kg of sugar bought on the third day.

4. Subtract the amount of sugar sold on the second day and the amount of sugar bought on the third day from the initial amount of sugar to find the remaining amount: - The initial amount of sugar in the store was 392 kg. - Subtracting the sugar sold on the second day (43.5 kg) and the sugar bought on the third day (21.75 kg) from the initial amount gives us: - 392 kg - 43.5 kg - 21.75 kg = 326.75 kg of sugar remaining in the store.

Therefore, there are 326.75 kg of sugar remaining in the store.
