Question 32

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 W.
II. Some R are X.

Conclusions:
I.Some W are not X.
II. No W is R.

Solution

Conclusion: I. Some W are not X.

As per the above-given Venn diagram, there is a completely negative relationship between 'W' and 'X'. So the relation of 'some not' will be definitely true. The given conclusion follow.

Conclusion: II. No W is R.

As per the above-given Venn diagram, we can definitely say that 'some R are not W.'. But a completely negative relation between them cannot be concluded. So the given conclusion does not follow.

Hence only conclusion I follow.
