Answer:
Saturated salt water evaporates quicker than saturated sugar water due to the fact that salt's saturation point is lower than sugar water.
Added information: It depends on the relative concentrations of the solutions. A one molar solution of sugar (342 g sucrose per L) will have the same vapour pressure as 1.9 molar solution(111 g of salt per L) of sodium chloride (table salt). That all means that if you dissolve 342 g of sugar in a litre of solution, and 111 g of table salt in a litre of solution, these two solutions will initially evaporate at the same rate. Mass for mass concentrations, therefore, sugar water will evaporate faster than salt water.
