(i) The density of the solid is 950 kg/m³
(ii) the density of another liquid in which the same solid would float is 200 kg/m³
The given parameters;
mass of the solid in air, Ma = 237.5 g
mass of the solid in liquid, Ms = 12.5 g
density of the liquid, 
(i) The density of the solid is calculated as follows;
Weight in air - Weight in liquid = upthrust

(ii) the density of another liquid in which the same solid would float with one-fifth of its volume exposed above the liquid surface.
This is a low density liquid, because one-fifth of the solid is above the liquid surface while four-fifth is below the liquid surface.
the specific gravity of the liquid = ¹/₅ = 0.2
density of water , 

Thus, the density of another liquid in which the same solid would float is 200 kg/m³
