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 rods. Some rods are chains. All chains are hammers.
Conclusions:
I. Some pins are hammers.
II. Some hammers are rods
III. No pin is hammer.
-
- Only I follows
- Only II follows
- Only III follows
- Only either I or III & II follows
- None of these
Correct Option: D
All pins are rods + Some rods are chains = A + I = No conclusion Hence I and II does not follow. However, the two a complementary I-E pair, Hence either I or III follows. Some rods are chains + All chains are Hammers = I + A + I = Some rods are hammers → conversion → Some hammers are rods (I). Hence III follows.
