NEET 2020 Chemistry question on States of Matter

A mixture of $\text{N}_2$ and Ar gases in a cylinder contains 7 g of $\text{N}_2$ and 8 g of Ar. If the total pressure of the mixture of the gases in the cylinder is 27 bar, the partial pressure of $\text{N}_2$ is :
[Use atomic masses (in g mol$^{-1}$) : N = 14, Ar = 40]
