In this logical reasoning question involving money, two statements relate notes, coins, and currency. You must regard the statements as true and decide which of the conclusions I and II logically follow. Statement I: Some notes are coins. Statement II: All notes are currency. Conclusion I: No coins are currency. Conclusion II: Some currency are coins.

Introduction / Context:
This problem uses familiar money related terms to frame a categorical logic question, but as always, you must ignore real world banking details and focus purely on the logical structure. There are three sets: notes, coins, and currency. The statements describe how notes relate to coins and currency, and the conclusions propose possible relationships between coins and currency. Your goal is to see what must be true in every scenario that satisfies the statements.

Given Data / Assumptions:
- Statement I: Some notes are coins, meaning there is at least one item that is both a note and a coin.
- Statement II: All notes are currency, meaning the set of notes lies entirely inside the set of currency.
- Conclusion I: No coins are currency, which states that coins and currency are completely disjoint sets.
- Conclusion II: Some currency are coins, which claims that there is at least one element common to both currency and coins.

Concept / Approach:
We translate everything into set relationships. Let N be the set of notes, C be the set of coins, and R be the set of currency. Statement I gives N ∩ C is non empty. Statement II gives N ⊆ R. From these, we can deduce information about the intersection of C and R. Then we check if each conclusion is logically consistent with these relations. A conclusion is valid only if it holds in every possible configuration that respects the given statements.

Step-by-Step Solution:
Step 1: Because some notes are coins, there exists at least one element x such that x ∈ N and x ∈ C. Step 2: Since all notes are currency, if an element is in N, then it must also be in R. So x ∈ N implies x ∈ R. Step 3: Therefore, x belongs to N, C, and R simultaneously. Hence x is in C ∩ R, which proves that the intersection of coins and currency is non empty. Step 4: This directly supports Conclusion II, which states that some currency are coins. Step 5: Conclusion I says that no coins are currency, meaning C ∩ R is empty. However, we have just shown that at least one element belongs to both sets. Step 6: Therefore Conclusion I contradicts the information in the statements and cannot be true in any configuration that satisfies them.

Verification / Alternative check:
Draw a circle N for notes inside a larger circle R for currency. Then mark a region where N overlaps with another circle C for coins. That overlapping region is notes that are also coins and therefore also currency. In this diagram, C and R clearly intersect, which makes Conclusion II true. But you cannot draw any valid diagram satisfying both statements where C and R do not intersect, so Conclusion I must always be false.

Why Other Options Are Wrong:
Option A chooses Conclusion I, which we have shown contradicts the statements. Option C says both conclusions follow, but they are mutually inconsistent because one says no intersection and the other says some intersection. Option D says neither follows, which ignores the firm deduction that some currency must be coins. Option E is incorrect because coins and currency are not independent; they definitely intersect due to the overlapping notes.

Common Pitfalls:
Some students are misled by the everyday idea that notes and coins are separate forms of money and may think of them as disjoint. However, the question explicitly tells you that some notes are coins, so you must abandon real life intuition. Always work from the statements themselves, and remember that "some" indicates at least one common element in the intersection.

Final Answer:
The correct option is Only conclusion II follows, because the statements guarantee that some currency items are also coins, while the claim that no coins are currency directly contradicts the given information.
