Question
A solid of density 900 kg/m3 floats in oil as shown in the given diagram. The oil floats on water of density 1000 kg/m3 as shown. The density of oil kg/m3 could be :
Options
850
900
950
1050

Solution
950.
The solid object floats in oil because the density of the solid object is less than the oil. The oil floats in water because the density of oil is less than water. Thus, the density of oil must be between density of solid and water.
