# A Piece Of Solid Weighs 120 G In Air, 80 G In Water And 60 Kg In A Liquid. The Relative Density Of The Solid And That Of The Liquid Are Respectively:

Given:

Weight of a solid in air = 120g

Weight of a solid in water = 80g

Weight of a solid in liquid = 60kg

Relative density of solid = $$\frac{W_{(air)}}{W_{(air)} – W_{(water)}}$$ $$\Rightarrow \frac{120}{120-80}$$ $$\Rightarrow \frac{120}{40}$$ $$\Rightarrow 3$$

Relative density of solid = $$\frac{W_{(air)} – W_{(liquid)}}{W_{(air)} – W_{(water)}}$$ $$\Rightarrow \frac{120 – 60}{120 – 80}$$ $$\Rightarrow \frac{60}{40}$$ $$\Rightarrow \frac{3}{2}$$

Therefore, the relative density of the solid is 3 and the relative density of the liquid is $$\frac{3}{2}$$, respectively
