The grain-size distribution of two soils is provided below. The liquid and plastic limits of No. 40 sieve fraction of the soil are as follows: Soil A: Liquid Limit = 30, Plastic Limit = 22 Soil B: Liquid Limit = 26, Plastic Limit = 20 No. 200 sieve 100 80 Percent finer 8 20 0 1.0 D60 D30 D10 Soil A Soil B 0.1 0.01 Particle diameter (mm)-log scale 0.001 Determine the group symbols and group names according to the Unified Soil Classification System, for Soil A and Soil B
