Problem Analysis

To solve this problem, we need to determine the amount of fresh plums needed to obtain 35 kg of dried plums. We are given that from 60 kg of fresh plums, we obtain 21 kg of dried plums. We can use this information to calculate the ratio of fresh plums to dried plums and then use that ratio to find the amount of fresh plums needed for 35 kg of dried plums.

Solution

Let's calculate the ratio of fresh plums to dried plums: - Ratio = (Amount of fresh plums) / (Amount of dried plums) - Ratio = 60 kg / 21 kg - Ratio = 2.857

Now, we can use this ratio to find the amount of fresh plums needed for 35 kg of dried plums: - Amount of fresh plums = (Amount of dried plums) * (Ratio) - Amount of fresh plums = 35 kg * 2.857 - Amount of fresh plums ≈ 100 kg

Therefore, approximately 100 kg of fresh plums are needed to obtain 35 kg of dried plums.

Answer

To obtain 35 kg of dried plums, approximately 100 kg of fresh plums need to be taken.
