Solution

Dear visitors, thank you for your effort and solutions. The fist to send correct solution was Holger. Well done. Congratulations!

Here is my solution:

650x0-84=546 tons. This is the quantity of pure wood in the stock. 546 tons is 91% of the new weight.

100% is 54600/91=600 tons.

The new weight of the stock is 600 tons.
