Heat And Thermodynamics

A jar '\(\mathrm{P}\)' is filled with gas having pressure, volume and temperature \(\mathrm{P}, \mathrm{V}, \mathrm{T}\) respectively. Another gas jar \(Q\) filled with a gas having pressure \(2 \mathrm{P}\), volume \(\frac{\mathrm{V}}{4}\) and temperature \(2 \mathrm{~T}\). The ratio of the number of molecules in jar \(\mathrm{P}\) to those in jar \(Q\) is
