Calculation of Remaining Watermelons

To calculate the number of kilograms of watermelons that remained unsold, we need to follow the given information step by step.

1. The store received 3 and 4/5 tons of watermelons. 2. On the first day, 80% of all the watermelons were sold. 3. On the next day, 15/19 of the remaining watermelons were sold.

Let's break down the calculation:

Step 1: Convert tons to kilograms: - 1 ton = 1000 kilograms - 3 and 4/5 tons = 3.8 tons = 3.8 * 1000 kilograms = 3800 kilograms.

Step 2: Calculate the number of watermelons sold on the first day: - 80% of 3800 kilograms = 0.8 * 3800 kilograms = 3040 kilograms.

Step 3: Calculate the remaining watermelons after the first day: - Remaining watermelons = Total watermelons - Watermelons sold on the first day - Remaining watermelons = 3800 kilograms - 3040 kilograms = 760 kilograms.

Step 4: Calculate the number of watermelons sold on the second day: - 15/19 of the remaining watermelons = (15/19) * 760 kilograms = 600 kilograms.

Step 5: Calculate the remaining watermelons after the second day: - Remaining watermelons = Remaining watermelons - Watermelons sold on the second day - Remaining watermelons = 760 kilograms - 600 kilograms = 160 kilograms.

Therefore, there are 160 kilograms of watermelons that remained unsold.
