Answer 2

Calculation of Raisins from Grapes

To calculate the amount of raisins obtained from the grapes, we need to determine the weight of the grapes and then calculate one-fourth of that weight.

Given: - On the first day, 80 kg of grapes were collected, which is twice the amount collected on the second day.

Let's calculate the weight of grapes collected on the second day: - If the weight of grapes collected on the second day is x kg, then the weight of grapes collected on the first day is 2x kg.

To find x, we can set up the following equation: 2x = 80

Solving for x: x = 80 / 2 x = 40 kg

Therefore, the weight of grapes collected on the second day is 40 kg.

Now, let's calculate the weight of raisins obtained from the grapes: - The weight of raisins obtained is one-fourth of the weight of grapes collected.

To find the weight of raisins, we can calculate one-fourth of the total weight of grapes collected: Weight of raisins = (1/4) * (80 + 40) kg

Calculating: Weight of raisins = (1/4) * 120 kg Weight of raisins = 30 kg

Therefore, 30 kilograms of raisins were obtained from the grapes, considering that the weight of raisins is one-fourth of the total weight of grapes collected.
