Two liquids A and B are partially miscible (Molecular mass A=20, Molecular mass B=40). On mixing 1 mol of A with 3 moles of B, two different layers M and N are formed with layer M containing 0.2 mole fraction of A and layer N containing 0.6 mole fraction of A. The ratio of masses of layer M to layer N will be :
