Two clay layer of A and B of thickness 2cm and 3 cm is load with pressure of 200KN/m^2. If the time taken by soil A to reach 50% consolidation is 1/4^th of that required by soil B to reach 50% consolidation, then find the ratio of coefficients of Permeability. Given that ratio of coefficient of volume change is 1.751.
