Question

In a wet soil mass, air occupies one-fourth of its volume and water occupies one-half of its volume. The void ratio of this soil is:

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

(c)

$V_a=V/4,V_W=V/2$

$\therefore V_V=\frac{V}{4}+\frac{V}{4}=\frac{3V}{4}$

$\therefore e=\frac{V_v}{V_s}=\frac{\frac{3V}{4}}{V-\frac{3}{4}V}=\frac{\frac{3V}{4}}{\frac{V}{4}}=3$
