Chemical Kinetics · Pressure change in gas phase kinetics

Consider the following gas phase reaction being carried out in a closed vessel at 25 $^\circ$ C.

$\ce{2A(g) -> 4B(g) + C(g)}$

$\dfrac{\text{time}}{\text{(min)}}$	$\dfrac{\text{total pressure of the system}}{\text{(mm Hg)}}$
30	300
$\infty$	600

The pressure of C(g) at 30 minutes time interval would be mm Hg. (Nearest integer)
