Statements: All mangoes are golden in colour. No golden-coloured things are cheap.

Conclusions:

1. All mangoes are cheap.
2. Golden-coloured mangoes are not cheap.
Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow
Explanation:
Clearly, the conclusion must be universal negative and should not contain the middle term. So, it follows that 'No mango is cheap'. Since all mangoes are golden in colour, we may substitute 'mangoes' with 'golden-coloured mangoes'. Thus, II follows.

Can anyone give the proper explanation to understand this?

How do we add the middle term in conclusion?

The golden colour is middle term a subject in the major premise.

As per the syllogism, condition 1 also follows.

Here, We have to consider the negative part of the universe.

Since middle term is coming in the second conclusion it won't follow (Rule 1). So option E and B can be eliminated. Then from Rule 6 we know if one premise is negative conclusion must be negative so conclusion 1 also won't follow. So option A and option C can be eliminated. Then D will be answer I guess.

We know middle term should not be used in the conclusion. Here golden colour is middle term then how it can be used in the conclusion. So its answer should be no conclusion would follow.

All gold colour things are not cheap that means they are expensive.

So only 2 follows.

The mango is a golden thing, and all golden things are expensive, so the mango would be expensive.

We cannot substitute mangos instead of golden color.

But in the second premise, only 'things' are said! No scene of mango in there! then why conclusion II?
