Question 50

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statements:
I. No X is G.
II. All B are X.

Conclusions:
I. Some G are B.
II. All X are B.

Solution

Conclusion: I. Some G are B.

As per the above-given Venn diagram, we can definitely say that 'no G is B.'. So the relation of 'some' cannot happen. The given conclusion does not follow.

Conclusion: II. All X are B.

As per the above-given Venn diagram, we can only say that 'some X are B.'. But the relation of 'all' cannot be said. So the given conclusion does not follow.

Hence none of the given conclusions follow.
