Problem Statement

You are given that a fresh apple contains 80% water, and after drying in a drying oven, it contains 20% water. The question is: how many kilograms lighter will 100 kg of fresh apples become after drying in the oven?

Solution

To solve this problem, we need to calculate the weight of water in the fresh apples and the weight of water in the dried apples. The weight difference between the two will give us the answer.

Let's assume that the weight of water in 100 kg of fresh apples is W1 kg. Since the fresh apples contain 80% water, we can calculate W1 as follows:

W1 = 80% of 100 kg

To find the weight of water in the dried apples, we can calculate W2 using the same approach. Since the dried apples contain 20% water, we have:

**W2 = 20% of 100 kg
