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 ${\text{KNO}}_{3}$ is 40 g/100 mL of water.

Thus, if you start with a solution having 40 g of ${\text{KNO}}_{3}$ in 100 mL of water at 100 °C and cool it to 25 °C, it will still hold 40 g of dissolved ${\text{KNO}}_{3}$.

The solution will be saturated, but no ${\text{KNO}}_{3}$ will precipitate.
