After developing a compaction curve in the lab, you have determined the maximum dry density $)$ and the corresponding optimum moisture content $(7\%)$ of your soil sample.

What is the relative compaction achieved by the contractor, if the actual dry density and water content measured in the field are $80l\frac{b}{f}{t}^3$ and $12\%,$ respectively.

$120\mathrm{.}0\%$

$12\mathrm{.}0\%$

$14\mathrm{.}4\%$

$66\mathrm{.}6\%$
