Calculating the Amount of Biscuits Sold on the First Day

To calculate the amount of biscuits sold on the first day, we can use the information provided and the total amount of biscuits available.

Given: - Biscuits sold on the first day: 12 boxes - Biscuits sold on the second day: 8 boxes - Total biscuits available: 240 kg

Let's calculate the amount of biscuits sold on the first day.

Step 1: Calculate the total number of boxes sold. - Total boxes sold = 12 (first day) + 8 (second day) = 20 boxes

Step 2: Calculate the amount of biscuits sold on the first day. - Biscuits sold on the first day = (Total biscuits / Total boxes) * Biscuits sold on the first day - Biscuits sold on the first day = (240 kg / 20 boxes) * 12 boxes - Biscuits sold on the first day = 12 kg per box - Biscuits sold on the first day = 12 kg/box * 12 boxes = 144 kg

Therefore, 144 kilograms of biscuits were sold on the first day.
