Given:- G=2.67, e=0.63
V=1000mL
mloose=1475gm
mcompcat=1770gm
$sd(min)=\frac{1475}{1000}=1.475g/cm^{3}$
$sd(min)=\frac{G.Pw}{1+emax}$, emax=0.81
sd(max)=$\frac{1770}{1000}=1.77g/cm^{3}$
emin=$\frac{G sw}{(sd)}_{max}-1$=0.508
$I_{D}\frac{emax-e}{emax-emin}$
$\frac{0.81-0.63}{0.81-0.508}$
$I_{D}$=0.596
$I_{D}$=59.6%
