Answer & Solution
Correct Answer:
Option
B
According to Atterberg, the soil is said to be of medium plasticity if the plasticity index (PI) is
The plasticity index (PI) is a measure of the plasticity of a soil and is calculated as the difference between the liquid limit (LL) and the plastic limit (PL).
Soils with a PI between 7 and 17 are considered to have medium plasticity. This range indicates moderate changes in consistency with changes in moisture content.
Therefore, the correct option is 7 < PI < 17.

Login0=Non-plastic
1–5=Slightly plastic
5–10=Low plasticity
10–20=Medium plasticity
20–40=High plasticity
>40=Very high plasticity
0-5 SLIGHTLY PLASTIC
5-10 LOW PLASTIC
10-20 MEDIUM PLASTIC
20-40 HIGH PLASTIC
>40 VERY HIGH PLASTIC
3-15= slightly plastic
15-30= medium plastic
>30 = high plastic
so the ans must be= 17
0-7 low plastic
7-17 medium plastic
>17 high plastic
