Answer 2

Here we will first do sedimentation process. Because of this, the sawdust being the heavier particle gets settled at the bottom of the container along with sand. The mixture is then separated from sawdust and sand by filtration.
After filtration, we will get the mixture of water and salt. This mixture is then separated by using evaporation. During evaporation, the water molecules get evaporated leaving behind only salt particles.
