Statement:
Some bags are plates. Some plates are chairs. All chairs are tables.
Conclusions:
I. Some tables are plates.
II. Some chairs are bags.
III. No chair is bag.

Some pates are chairs + All chairs are tables = I + A = I = Some plates are tables ? conversion ? Some tables are plates(I). Hence I follows. Some bags are plates + Some plates are chairs = I + I = No conclusion Hence II and III do not follow. By combination. However, the two form a complementary E-I pair, Hence either I or III follows.
