Explanation:

The volume of $C_{2} H_{4}$ in 50 ml of sample is 50ml × $\frac{40}{100}$ = 20 ml

The volume of C$H_{4}$ in 50 ml of sample is 50ml ×$\frac{60}{100}$ = 30ml

$CH_{4}$    ⇒    $CO_{2}$        + $2H_{2}O$

3o ml       30 ml          60 ml

$C_{2}H_{2}$    ⇒   $2 CO_{2}$      + $2H_{2} O$

20ml          30 ml         40 ml

The volume of CO2 formed = 30ml+40ml = 70 ml
