First Write the half chemccal eqns of each compound and balance it.
Half-reactions:
 3I2 + C2H5OH + 2OH- --> 2CHI3 + 3H2O + 2e-
This was for Iiodine

C2H5OH + 10OH- --> 2HCOO- + 7H2O + 8e- 
This was for C2H5OH.
Now Adding both the eqns we get,
2C2H5OH + 3I2 + 12OH- -> 2CHI3 + 2HCOO- + 10H2O + 10e-
simply which would be the final balanced redox recation.
