40% of total volume = 120 ml of 200 ml.
Balanced eqn. for each compound, 
        CH4 + 2O2   ---------->            CO2   +   2H2O  
         V ml                                         V ml
 
        CO          +       ½ O2      ------->    CO2
       (120 – V) ml                                  (120 – V) ml
 
C4H10       +          13/2 O2     ----------->   4CO2    +    5 H2O
120 ml                                                       v/4
                                                               v = 480 ml.
 
Hence total volume of CO2 => 480 ml + V + 120 – V => 600 ml.
