Water hyacinth float on water surface. Explain.

A body floats with one-third of its volume outside water and 3//4 of its volume outside another liquid. The density of another liquid is :

A body floats on water with one third of its volume above the surface of water. If it is placed in oil, it floats with half of its volume above the surface of the oil. The specific gravity of the soil is
