Actually, Solution is type of homogeneous mixtures. Ahomogeneous mixtureis a solid, liquid or gaseousmixturethat has the same proportions of its components throughout a given sample (or multiple samples of different proportion). Homogeneous mixtures can have a variable composition. Examples of homogeneous mixtures: Solutions, Air, alloys etc. actually, two terms are used to separate homogeneous and heterogeneous mixtures as if there would not have been this type of segregation then the mixture would have been separated as Solutions, air, alloys etc (homogeneous) and colloids, suspensions etc (heterogeneous) which would have been quite tedious work.
