Question

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:
1. All Z are Y.
2. Some Y are B.
conclusion:
I. Some B are not Z.
II. Some Y are not Z.
III. Some Z are Y.

Both conclusions I and III follows

All conclusion follows

Only conclusion III follows

Both conclusions II and III follows

Solution

Correct option is C

From the given statement following Venn diagram will be drawn -

Conclusion I: "Some B are not Z."

Conclusion I does not follow because we cannot definitively state that "Some B are not Z" based solely on the given information.

Conclusion II: "Some Y are not Z."

Since all Z are Y, it does not imply that "some Y are not Z." There is no information suggesting that Y extends beyond Z or that any part of Y is outside Z.

Conclusion II does not follow because we cannot conclude that "some Y are not Z" with certainty.

Conclusion III: "Some Z are Y."

This conclusion follows logically because if all Z are Y, then it’s naturally true that some part of Z is also Y (since Z is fully contained within Y).

Conclusion III follows.

Correct Answer: (c) Only Conclusion III follows.
