The answer is 75% Hydrogen and 25% Methane (Rates of leakage is independent of the composition of the mixture). It only depends on the individual molecular weights of the gas.

Sorry fr my incorrect response. Actually i didnt took their respective partial pressures in consideration.

The correct answer is 51% and 49% respectively.

This can be derived with the use of the grahams law of diffusion

r1/r2= (P1/P2)(root (M2/M1))

Where P1 and P2 r their respective partial pressures and M1 and M2 r their respective Molecular masses
