Statement: Some tyres are rains. Some rains are flowers. All flowers are jungles. All jungles are tubes. Conclusions: I. Some jungles are tyres. II. Some tubes are rains. III. Some jungles are rains. IV. Some tubes are flowers.

All flowers are jungles + All jungles are tubes = A + A = A = All flowers are tubes → conversion → Some tubes are flowers (I) Hence Iv follows. Some rains are flowers + All flowers are tubes = I + A = I = Some rains are tubes → conversion → Some tubes are rains (I) Hence II follows. Some rains are flowers + All flowers are jungles = I + A = I = Some rains are jungles → conversion → Some jungles are rains (I) Hence III follows. Some tyres are rains + Some rains are jungles = A + I = No conclusion Hence I does not follow.
