Hey Student..
As per what is required in this question, you need to take into account the basics of general oxidation states. As for example O has -2, H as +1, Fe as +2 or +3 according to the ligands so present..
just take into account this hint and try calculating the oxidation state..

THE ANSWER IS FeCrO4 SINCE THE OXIDATION STATE OF FE=+2,
CR =x, O=-2
THEN (+2)+(x)+4(-2)=0
x-6=0
x=6
THERE FORE OXIDATION STATE OF CR =6 IN FeCrO4
HENCE PROVED . THANK YOU
