A sphere is floating in water its 13rd part is outside the water and when the sphere is floating in unknown liquid, it's 34th part is outside the liquid than the density of the liquid is
volume of liquid inside the liquid1=2/3rd of total volume
volume of liquid inside the liquid2 = 1/4th of total volume
density of liquid= (2/3)/(1/4) = 8/3 g/cc
