There are nuts in three boxes. In the first box, there are 6 kg fewer nuts than in the other two together. And in the second box, there are 10 kg fewer nuts than in the other two together. How many nuts are in the third box?
Let's combine both given conditions and obtain the following statement: "In the first and second boxes, there are $6+10$ kg fewer nuts than in the first, second, and two-thirds of the third box." From this, it follows that in two-thirds of the third box, there are 16 kg of nuts, which means that in the third box, there are 8 kg of nuts.

## Answer

8 kg.
