Nothing will precipitate.

Explanation:

I assume that you are being asked to interpret a solubility graph something like this.

From the graph, it appears that the solubility of "KNO"_3KNO3 is 40 g/100 mL of water.

Thus, if you start with a solution having 40 g of "KNO"_3KNO3 in 100 mL of water at 100 °C and cool it to 25 °C, it will still hold 40 g of dissolved "KNO"_3KNO3.

The solution will be saturated, but no "KNO"_3KNO3 will precipitate.
