Three dielectrics of relative primitivities `varepsilon_{eta}=6, varepsilon_{r/2} = 2` and `varepsilon_{r/3}=3` are introduced in a parallel plate capacitor of plate area `A` and separation `d`, as shown in the figure. If the effective capacitance between points `P` and `Q` is `{x varepsilon_{0} A}/{d}`, then `{5}/{7} x` will be
