If: $C_u>6C_u\frac{n}{a}$; and $C_u>6,$ the sample $is$ well graded, otherwise, the sample $is$ poorly graded.

$If$ the sample $is$ poorly graded and $C_{u}is$ less than $or$ equal $to2\mathrm{.}0,$ the sample $is$ uniform.

$Is$ the sample well graded $or$ poorly graded?

$If$ the sample $is$ poorly graded, $isit$ uniform:

Fines:$\frac{n}{a}$; fines $(-200)$
