A mixture contains three different substances X, Y and Z. They are of the same size, cubical in shape and yellow in colour. X particles are very heavy, insoluble, non-magnetic and contribute 50 of the mixture. Y particles are very light, insoluble, non-magnetic and contribute 40 of the mixture. And Z particles are iron pieces.
