Equal amounts can be dissolved at 58 °C.

Explanation:

I presume that you are asked to interpret a solubility curve like the one below.

Solubility
(Adapted from KentChemistry HOME)

Find the curves for #"NH"_4"Cl"# and #"HCl"# and locate the point where they cross.

Then, drop a line down to the temperature axis and note the temperature.

In this diagram, it looks like both compounds have the same solubility (about 56 g/100 g of water) at 58 °C.
