Given,Weight of the solid in air (W1) = 120 gfWeight of the solid when completely immersed in water (W2) = 105 gfRelative density of solid=(W1W1−W2)=(120120−105)=8\text{Relative density of solid} = \big(\dfrac{\text W_{1}}{\text W_{1} − \text W_{2}}\big) \[0.5em] = \big(\dfrac{120}{120 - 105}\big) \[0.5em] = 8Relative density of solid=(W1​−W2​W1​​)=(120−105120​)=8∴ Relative density of solid = 8
