We know that
K = CD102
where C is shape co-efficient.
Therefore, approximate ratio will be = (0.62)/(0.32) = 4
K = CD102
where C is shape co-efficient.

Explanation:
Permeability of soil is directly proportional to the square of the effective size of soil particles. The effective size of soil particles is defined as the size of aperture through which 10% of soil particles pass.
Given D10 of two soils is 0.6 mm and 0.3 mm respectively.
To find ratio of permeability, we need to find the ratio of square of effective size.
Let D10 of first soil = 0.6 mm
Effective size of first soil = 0.6/2 = 0.3 mm
Let D10 of second soil = 0.3 mm
Effective size of second soil = 0.3/2 = 0.15 mm
Ratio of effective size = 0.3^2/0.15^2 = 4
Therefore, the ratio of permeability of two clean soils having D10 = 0.6 mm and D10 = 0.3 mm is 4.
