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 pins are bags. All chalks are bags. All needles are bags.
Conclusions:
I. Some needles are pins.
II. Some chalks are needles.
III. No needle is pin.
-
- Only I follows
- Only III follows
- Only either I or III follows
- Only either I or III and II follows
- None of these
Correct Option: C
All pins are bags (A) → conversion → Some bags are pins (I). All needles are bags + Some bags are pins = A + I = No conclusion Hence I and III do not follow by combination. However, they from an complementary E-I pair, either I or III follows. Again, All chalks are bags + conversion of all needles are bags = A + I = No conclusion Hence II do not follow.
