How to do question 68

Solution :

Density of solid = 900 kg/m3
Density of water = 1000 kg/m3
As we know that, a matter floats on the liquid if it's Density is less than that of that liquid. Here, solid floats on oil, while oil floats on water. So, the density should be in between 900 and 1000. Hence, the correct option will be (c) 950 kg/m3.
