Correct Answer - Option 3 : 7.8%

Concept:

Water content formula is given by:

w = Ww/Ws

where,

w = Water content

Ww = Weight of water

Ws = Weight of solids

Calculation:

Given data:

Weight of water (Ww) = 2.16 gm

Weight of dry soil or weight of solid (Ws) = 27.63 gm

So, Water content, w = $2.16 \over 27.63$ = 0.0781

Water content (w) = 7.81%
