Kinetic Theory of Gases Questions

At $10^{\circ }\text{C}$, the value of the density of a fixed mass of an ideal gas divided by its pressure is $x$. At $110^{\circ }\text{C}$, this ratio is:

Two vessels separately contain two ideal gases $A$ and $B$ at the same temperature, the pressure of $A$ being twice that of $B$. Under such conditions, the density of $A$ is found to be $1.5$ times the density of $B$. The ratio of molecular weight of $A$ and $B$ is:
