Two bodies of identical size but made of different materials remain immersed completely in water. One of them remains suspended with the help of a thread and the tension acting on that thread is 500gxxg . The other is anchored to the bottom of the vessel by a thread so that it cannot float up and the tension acting on this thread is 12.5gxxg . If the volume of each body is 50cm^(3) , then determine the mass and density of each body.

A liquid of mass m_(1) and density rho_(1) is mixed with another liquid of mass m_(2) and density rho_(2) . If the volume of the mixture does not change, then what will be the density of the mixture?
