Read the given statements and conclusions carefully. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. You have to decide which conclusion(s) logically follow(s) from the given statements. Statements: All stamp are logo. All stamp are cheque. All stamp are document. Conclusions (I): All logo are document. Conclusions (II): Some document are cheque.

Correct Answer: Only conclusion (II) follows

Step-by-step Explanation:

Let us analyze the given statements and check the validity of each conclusion using logical reasoning and Venn diagrams / set theory principles.

Given Statements:
1. All stamp are logo. (Stamp ⊆ Logo)
2. All stamp are cheque. (Stamp ⊆ Cheque)
3. All stamp are document. (Stamp ⊆ Document)

Evaluating Conclusion (I): All logo are document.
From Statement 1, we know that all stamps are logos, which means the set of "Stamp" is inside the set of "Logo". From Statement 3, all stamps are documents, which means the set of "Stamp" is inside the set of "Document". However, this does not mean that every logo must be a document. There can be logos that are not stamps and fall outside the "Document" set. Therefore, Conclusion (I) does not logically follow.

Evaluating Conclusion (II): Some document are cheque.
From Statement 3, all stamps are documents, meaning there exists at least some documents that are stamps (since the set "Stamp" is non-empty and entirely inside "Document"). From Statement 2, all stamps are cheques. Thus, the stamps that are documents are also cheques. Therefore, there is definitely an intersection between the set of "Document" and the set of "Cheque". Hence, "Some document are cheque" is definitely true and Conclusion (II) logically follows.

Conclusion:
Only conclusion (II) logically follows from the given statements.
