Answer 2

Weighing 800g of Oil with 1kg, 500g, and 200g Weights

To weigh 800g of oil using 1kg, 500g, and 200g weights, you can follow these steps:

1. Using the 1kg Weight: Place the 1kg weight on one side of the balance scale and the oil on the other side. The scale will tip down on the side of the oil, indicating that the oil weighs less than 1kg.

2. Using the 500g Weight: Now, remove the 1kg weight and replace it with the 500g weight. Add additional weights to the oil side until the scale balances. This will indicate that the oil weighs 500g plus the additional weights used.

3. Using the 200g Weight: Finally, remove the 500g weight and replace it with the 200g weight. Add additional weights to the oil side until the scale balances. This will indicate that the oil weighs 200g plus the additional weights used.

By following these steps, you can determine that the oil weighs 500g (using the 500g weight) plus 200g (using the 200g weight) for a total of 700g. To measure the remaining 100g, you can use smaller weights or estimate based on the scale's markings.
