The determination of the plasticity index and the percentage by weight of clay mineral finer than 2μ present in the soil was done for two soil samples A and B. The ratio of plasticity index to the percentage of clay size particles for samples A and B are given in the table.

Soil Sample Index of percentage of clay size particle
Sample A Less than 0.75
Sample B Greater than 1.25

The two soil samples A and B are classified as:
