Direction: In each of the question below are Four statements following by Four conclusions numbered I, II, II and IV. You have to take the Four 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 stones are hammers. No hammer is a ring. Some rings are doors.
All doors are windows.
Conclusions:
I. Some windows are stones.
II. Some windows are rings.
III. No window is a stone.
IV. Some rings are stones.
-
- Only I follows
- Only II follows
- Only III follows
- Only either I or III follows
- Only either I or III and II follows
Correct Option: E
Some rings are doors + All doors are windows = I + A = I = Some rings are windows → Conversion → Some windows are rings(I) Hence II follows. All stones are hammers + No hammer is a ring = A + E = E No stones is a ring → conversion → No ring is a stone (E) Hence IV does not follows. No stone is a ring + Some rings are doors = E + I = O* = Some windows are not stones Hence either I or II follows as they form a complementary I-E pair.
