[ Void ratio is usually used in parallel with soil porosity (n) , which is definedas the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) ]

Void ratio is defined as the ratio of the weight of water in the soil to the weight of solids in the given mass of soil.
The Specific gravity of the soil is given as = 2.5
The weight of dry soil sample = 100 gms.
The volume of the given sample = 60 ml.
Void ratio = Vw / Vs
Vs = 100 / 2.5 = 40.
So, e = 60/40 = 1.5.
The Void ratio is = 1.5.
