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 chairs are keys. All keys are balloons. Some balloons are mirrors.
Some mirrors are desks.
Conclusions:
I. Some desks are keys.
II. Some balloons are mirrors.
III. Some mirrors are balloons.
-
- Only I follow
- Only II follows
- Only III follow
- Only II and III follow
- All I, II and III follow
Correct Option: D
All keys are balloons + Some balloons are mirrors = A + I = No conclusion Hence I does not follow. All chairs are keys + All keys are balloons = A + A = A = All chairs are balloons → conversion → Some balloons are chairs (I) Hence II follows. Some balloons are mirrors (I) → conversion → Some mirrors are balloons (I) Hence III follows.
