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.

We may also say that,

According to rule - if any one statement is negative then both conclusion must be also be negative, But in this conclusion one are not negative.

So, only 2nd follows.

Since the 2nd premise is negative, how a conclusion can be formed ?

We are no way concern about "Golden-coloured mangoes", because the term is not there in both the premises.
