How would you separate a mixture of sugar and salt?

Solution
We will separate a mixture of sugar and salt by filtration followed by evaporation. In this process, solvent used is alcohol instead of water because of the difference in solubility of salt and sugar in alcohol. Salt is insoluble in alcohol but sugar is soluble in it. The undissolved salt can be obtained by filtration.
The filtrate now has only sugar dissolved in alcohol. On heating, alcohol evaporates and sugar is left behind.
