Direction: In each of the question below are three statements following by three conclusions numbered I, II and III. You have to take the three given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusion logically follows from the two statements disregarding commonly known fact.
-
Statement:
All desks are rooms. Some rooms are halls. All halls are leaves.
Conclusions:
I. Some leaves are desks.
II. Some halls are desks.
III. Some leaves are rooms.
-
- None follows
- Only I follows
- Only II follows
- Only III follows
- Only II and III follows
Correct Option: D
Some rooms are halls + All halls are leaves = I + A = I = Some rooms are leaves → conversion → Some leaves are rooms(I) Hence III follows. All desks are rooms + Some rooms are halls = A + I = No conclusion Hence II and consequently I do not follow.
