$\displaystyle \mathrm{A}(\mathrm{g}) \rightarrow 2 \mathrm{~B}(\mathrm{~g})+\mathrm{C}(\mathrm{g})$ is a first order reaction. The initial pressure of the system was found to be $\displaystyle 800$ mm Hg which increased to $\displaystyle 1600$ mm Hg after $\displaystyle 10$ min . The total pressure of the system after $\displaystyle 30$ min will be $\displaystyle \_\_\_\_$ mm Hg . (Nearest integer)
