In the following question below are given three statements followed by four conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: I. Some Toy are Red. II. No Red is a Pink. III. All Pink are Black. Conclusions: I. Some Red are Black. II. Some Black being Toy is a possibility. III. All Toy are Pink. IV. Some Pink being Toy is a possibility.

Conclusions:
I. Some Red are Black → False (It is possible but not definite).
II. Some Black being Toy is a possibility → True (Possibility is true).
III. All Toy are Pink → False (It can’t be possible as Some Toy are Red and No Red is Pink).
IV. Some Pink being Toy is a possibility → True (Possibility is true).
Hence, both II and IV conclusions follow
