Solution

Similarity: In both the cases, the mixture shows the properties of its constituents and the constituents can be separated by physical methods, such as filtration, evaporation, distillation etc.

Difference: Mixture of sugar and water is a homogeneous mixture and it is considered to be a solution. On the other hand, mixture of sand and sugar is a heterogeneous mixture.
