JEE Advanced 2024 Chemistry question on States of Matter

A closed vessel contains 10 g of an ideal gas $\mathbf{X}$ at 300 K, which exerts 2 atm pressure. At the same temperature, 80 g of another ideal gas $\mathbf{Y}$ is added to it and the pressure becomes 6 atm. The ratio of root mean square velocities of $\mathbf{X}$ and $\mathbf{Y}$ at 300 K is
