Question: The plot below shows the Modified Proctor compaction curve for a soil that is being used as fill at a site. A sand cone test

The plot below shows the Modified Proctor compaction curve for a soil that is
being used as fill at a site.
A sand cone test performed on the compacted fill shows 90 percent relative
compaction and the water content of the soil is 3 percent above optimum.
What is the degree of saturation (in percent) of the compacted soil? Specific
gravity of soil solids is 2.7.
Numerical answer to one decimal place.
The plot below shows the Modified Proctor
