Question 48

In the following question below are given some statements followed by some conclusions based on those statements. 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. All L are B.
II. No T is L.
III. Some R are T.
Conclusions:
I. Some T are R.
II. No B is T.
III. No L is T.

Solution

Conclusion: I. Some T are R.

From the above given Venn diagram, this conclusion follows.

Conclusion: II. No B is T.

Conclusion: III. No L is T.

From the above given Venn diagram, this conclusion follows.

Both conclusions I and III follow.
