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:

Some kites are rocks.

All rocks are stones.

Conclusions:

(I) Atleast some kites are stones.

(II) All stones are rocks.

ABoth conclusions (1) and (Il) follow.

BOnly conclusion (1) follows.

COnly conclusion (Il) follows.

DNeither conclusion (1) nor (II) follows.

Answer:

B. Only conclusion (1) follows.

Read Explanation:

Let’s recheck carefully using proper logic.

Given Statements:

  1. Some kites are rocks

  2. All rocks are stones

So we can write:

  • Kites ∩ Rocks ≠ ∅

  • Rocks ⊆ Stones

    Conclusion (I): At least some kites are stones

  • Some kites are rocks

  • All rocks are stones

So the kites that are rocks are definitely stones too.

Therefore, some kites are stones is TRUE

Conclusion (I) follows

Conclusion (II): All stones are rocks

We only know:

  • Rocks → Stones
    But not Stones → Rocks

So reverse is NOT valid.

Conclusion (II) does NOT follow

Final Correct Answer:

Only Conclusion (I) follows


If your source says “only II follows,” it is incorrect based on standard syllogism rules.
