The reason may be that, if "salt" is "Sodium Chloride", this cannot be more than about 24 or 25% in water. Any such as 50% or 60% is just not physically possible.

If you want to play in the fantasy anyway:
Let g = water to evaporate
10%2A60%2F%2810-g%29=50;
and solve for g.
...but this will still be physically impossible.
