If the coefficients of volume change and compressibility of a soil sample are respectively 6.75 x 10-2 and 3 x 10-2, the void ratio of the soil sample, is

Correct Answer: 1.25

Explanation:

Coeff.compressibility = Coeff.volume change/(1 + e).


(1 + e) = Coeff.volume change/Coeff.compressibility.


e = (Coeff.volume change/Coeff.compressibility) - 1.


e = ((6.75 x 10-2)/(3 x 10-2)) - 1.


e = 2.25 - 1.


e = 1.25.
