Solution

The correct option is B $800 k g / m^{3}$
Relative density of any body floating in water is given by $ρ_{r} = \frac{V_{i n}}{V_{t o t a l}}$

Here $\frac{V_{i n}}{V_{t o t a l}} = 0.8$

so $ρ_{r} = \frac{V_{i n}}{V_{t o t a l}} = 0.8$

Density of body = relative density x density of water

$ρ = 0.8 \times 1000 k g / m^{3} = 800 k g / m^{3}$
