Answer 1

Answer:

To separate a mixture of iron nails ,salt and stones ,Firstly use a magnet to separate iron nails from the mixture,secondly use handpicking to separate stones and the salt is itself left ,so separated.

Answer 2

Iron nails can be segregated by hands
Then to the rest of the mixture add water
Mix properly. Using filtration sand can be removed(sand will be left on the filter paper)
Then by the process of evaporation water will get evaporated and salt will be obtained. Hence all the components will be separated
