Answer:

They are equally soluble at 95 °C.

Explanation:

Find the solubility curves for #"KCl"# and #"KClO"_3# in the diagram and trace them until they cross (at the red dot).

Solubility curves

Then follow the red arrow straight down to the horizontal axis.

Note the temperature at which the arrow hits the axis (95 °C).

That is the temperature at which #"KCl"# and #"KClO"_3# are equally soluble.
