dear neha 
in brown ring complex fe got +1 oxidation state so, only strong ligand will pair up , 
one electron from 4s with unpair electron of 3d , 
so, now there will be 3 electrons and 6 unpaired one , 
so, here magnetic moment will be root 15 = 3.8 ( approx ) 
and hybridisation will be sp3d2 here , 
HOPE IT CLEARS NOW
