With salt being more dense than water, the mass of 1cm3 of water is less than that of 1cm3 of salt. By adding salt to water, the mass of the saltwater is increased more greatly than its volume, since 1cm3 of water has a mass of 1g. Therefore, by adding a generous amount of salt, the mass of the saltwater increased significantly, while the volume of it only increased by a little. Eventually, the density of the saltwater will increase so greatly it becomes higher than that of the egg, causing the egg to float.
For example, the egg has a density of 30g/cm3, and the water has a density of 1g/cm3. By adding salt, the density increases from 1g/1cm3 to 1.2g/1cm3. Eventually, it will hit a density of over 30/cm3, and with lesser density, the egg will float on the surface of the saltwater.
