0- NON PLASTIC
0-5 SLIGHTLY PLASTIC
5-10 LOW PLASTIC
10-20 MEDIUM PLASTIC
20-40 HIGH PLASTIC
>40 VERY HIGH PLASTIC
0-3= non plastic
3-15= slightly plastic
15-30= medium plastic
>30 = high plastic
so the ans must be= 17
0 non-plastic
0-7 low plastic
7-17 medium plastic
>17 high plastic
Answer should be 7-17
it is 7-17
It should be 17
