In wet soil mass, air occupies one-seventh of its volume and Water occupies one- eighth of its volume. What will be the ratio of volume of voids with respect to the total volume?

A)
0.286
B)
0.279
C)
0.329
D)
0.432

Correct Answer :   0.286

Explanation : Volume of Water Va= (1/7) total volume V
Volume of Water VW= (1/8) total volume V
Volume of voids Vv= Va + Vw
Vv=(1/7)V+(1/8)V
Vv=(15/56)V=0.268V.
