A body when fully immersed in a liquid of specific gravity 1.2 weights 44 gwt. The same body when fully immersed in water weights 50 gwt. The mass of the body is ____ grams

Let m be the mass and v be the volume of the body. Let $\sigma$ and $\rho$ be the density of liquid and water respectively. $\therefore \mathrm{mg}-\mathrm{\sigma V}g=44\mathrm{g}$

  $\mathrm{mg}-1.2\mathrm{Vg}=44\mathrm{g}---\left(1\right)$

$\mathrm{mg}-\mathrm{\rho Vg}=50\mathrm{g}-----\left(2\right)$

Solving equation 1 and 2 we get $\mathrm{m}=80 \mathrm{g}$
