A 650 gm soil sample was subjected to sieve analysis and the cumulative percentage retained on 4.75 mm, 2 mm, 1 mm, and 450 μ series were obtained as 130, 260, 455 and 585 g respectively. In reference to the cumulative percentage of particles retained on different sieves, choose the correct option(s) out of the given statements.
1
The soil sample is a coarse grained one.
2
The uniformity coefficient is 4.44
3
The coefficient of curvature is 1.11
4
