In a dehydration process the product which was a 80% moisture initially, has lost half of
its weight during processing.
What is the final moisture content?

In the dehydration process described, the initial product has 80% moisture by weight. When it loses half of its weight, we need to calculate the final moisture content.

### Let’s break it down:

1. **Initial Condition**:
   - Moisture content = 80%
   - This means that for every 100 kg of product, 80 kg is water and 20 kg is dry matter (solid).

2. **After Processing**:
   - The product has lost half its weight. Initially, the total weight was 100 kg, so after processing, the product weighs 50 kg.
   - The dry matter remains unchanged at 20 kg because only water is removed during dehydration.
   - Therefore, the remaining 50 kg consists of 20 kg of dry matter and 30 kg of water.

3. **Final Moisture Content**:
   - The moisture content is the ratio of water to the total weight of the product after processing.
   \[
   \text{Final Moisture Content} = \frac{\text{Weight of water}}{\text{Total weight}} \times 100
   \]
   Substituting the values:
   \[
   \text{Final Moisture Content} = \frac{30}{50} \times 100 = 60\%
   \]

Thus, the final moisture content of the product is **60%**.
