Measuring 4kg of Groats with 1kg, 2kg, and 5kg Weights

To measure 4kg of groats using only 1kg, 2kg, and 5kg weights, you can follow these steps:

1. Using the 5kg and 1kg weights: - First, measure out 3kg of groats using the 5kg and 1kg weights. This can be done by placing the 5kg weight on one side of the balance and the 1kg weight on the other side. This will give you a total of 6kg (5kg + 1kg). - Then, remove the 1kg weight, leaving only the 5kg weight on one side. This will leave you with 4kg of groats on the other side, as 6kg - 2kg = 4kg.

2. Using the 2kg and 1kg weights: - Alternatively, you can measure out 3kg of groats using the 2kg and 1kg weights. This can be done by placing the 2kg weight on one side of the balance and the 1kg weight on the other side. This will give you a total of 3kg (2kg + 1kg). - Then, add the 5kg weight to the side with the 2kg weight. This will give you a total of 8kg (5kg + 2kg + 1kg). - Finally, remove the 5kg weight, leaving only the 2kg and 1kg weights on one side. This will leave you with 4kg of groats on the other side, as 8kg - 4kg = 4kg.

So, by using a combination of the 5kg, 2kg, and 1kg weights, you can measure out 4kg of groats.
