This is my guess:

(i) (a/d) x (b/e) x (d/f) > bc/de Insuff: don’t know anything about “a” or “f”

(ii) since this statement is not related to d or e, we can cancel out “d x e” on both side of the > sign. Also, cancel out “b” on both sides…..

left only with (ad/f)>c………..and from (ii) don’t know anything about “c” Insuff

C: if combine both statements, you’re still left with (ad/f) > c. and with info on d or c, combining both statements really don’t bring anything new to the table.
