Solution

Out of sand, powdered glass and common salt, common salt is the only substance which is soluble in water. Both sand and powdered glass are insoluble in water. Hence when a mixture of these three substances in water is filtered, sand and powdered glass would be left on filter paper while common salt will be present in the filtrate.
