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 tables. All tables are desks. Some desks are benches. Some desks are sofas.
Conclusions:
I. Some benches are sofas.
II. Some sofas are tables.
III. Some benches are tables.
Iv. No chair is bench
-
- None follows
- Only I & II follows
- Only II & III follows
- Only I, II & III follow
- None of these
Correct Option: A
Some desks are benches → (I) conversion → Some benches are desks (I) + Some desks are sofas = I + I = No conclusion Hence I does not follow. All tables are desks + Some desks are sofas = A + I = No conclusion Hence II does not follow. All tables are desks + Some desks are benches + A + I = No conclusion Hence III does not follow. For the same reason IV too does not follow.
