A retaining wall of height 8 m retains dry sand. In the initial state, the soil is loose and has a void = ratio of 0.5, Yd = 17.8 kN/m3 and 0 = 30°. Subsequently, the backfill is compacted to a state where void ratio is 0.4, Yd = 18.8 kN/m3 and 0 35°, The ratio of initial passive thrust to the final passive thrust, according to Rankine's earth pressure theory, is
