Answer 1

Explanation:

decantation followed by sedimentation

Answer 2

Answer- (C) SEDIMENTATION FOLLOWED BY DECANTATION

EXPLANATION - When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
