Some bikes are cars.
Some cars are motors.
No motor is cycle.
I. Some cycle are definitely bikes.
II. At least some motors are bikes.
III. All cars being bikes is a possibility.
IV. No bike is cycle.
Some bikes are cars(I) + Some cars are motors(I) ⇒ No conclusion. Hence conclusion I, II and IV does not follow but conclusion I and IV will form a complementary pair. Hence either conclusion I or IV follow. Some bikes are cars(I) ⇒ Conversion ⇒ Some cars are bikes(I) ⇒ Probable conclusion ⇒ All cars being bikes is a possibility.(A). Hence conclusion III follows. ALTERNATE SOLUTION: Minimal possibility:
