Question

I was solving one question related to Syllogism. But I am not understanding the answer.

Is statement "No rings are bangles" equivalent to "No bangles are rings" in syllogism?

Question:

Statements :
No rings are bangles.
All gold are rings.

Conclusions :
I. No bangles are gold.
II. Some rings are gold.

a) Only conclusion I follows b) Both conclusions I and II follow
c) Only conclusion II follows d) Neither conclusion I nor conclusion II follows
e) None of these

Answer: c

As per my opinion answer should be b. Because if "No rings are bangles", to make 1st conclusion false there should be a case exists where at least one Bangle which is a Gold. If B=G exists then, as per statement all golds are rings. It means B=G=R. Which is contradicting the given statement.

Answer 1

A) Only conclusion I follow this is the correct ans
