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:

1. All engineers are graduates.

2. All graduates are successful.

Conclusions:

I. All successful are graduates

II. All engineers are successful.

From the statement following Venn diagram can be –

This conclusion implies that the group of successful people is entirely included in the group of graduates.

However, the statements do not support this. The statements only tell us that all graduates are successful, but not that all successful are graduates.

From Statement 1, all engineers are graduates.

From Statement 2, all graduates are successful.

Therefore, it logically follows that all engineers are successful, as they are a subset of graduates.

​Only Conclusion II follows.

Thus, correct answer is (b) Only II
