meq of iodine=11*5*0.5=27.5
meq of KMnO4=12.8*0.25*5*2=32
FeO.Fe2O3+Fe2O3→Fe2+→Fe3+
let the meq of FeO be x; Fe2O3(from Fe3O4) be y and Fe2O3 be z
x+y+z=32
y+z=27.5
so x=4.5
y=meq of Fe2O3(from Fe3O4)=4.5*2=9
meq of Fe2O3=27.5-9=18.5
% Fe2O3=(18.5*160/2)*100/(3*1000)=49.33%
%Fe3O4=(4.5*232)*100/(3*1000)=34.8%
