If a solution is made by dissolving 15g of each solid in the same 100g of water at 70 degrees and the solution is cooled to 20 degrees, crystals are observed.. Which solid crystallises and explain in reference to both solids

Do you expect us to be clairvoyant? What solids? What are the solubilities? Etc, The solid crystallizing first will be the less soluble one at 20 C.
why will the least soluble solution crystallise first?
