I bought the good and the bad books/ones.

[navi tasan]

1) I bought the good and the bad books.
2) I bought the good and the bad ones.

I wrote those sentences.

I think they mean:
a) I bought the good books/ones and the bad books/ones.

Could they ever mean the same as any of the following sentences?

b) I bought the good book/one and the bad book/one.
c) I bought the good book/one and the bad books/ones.
d) I bought the good books/ones and the bad book/ones.

This is really confusing! If someone walked up to you and said "I bought the good one", how could you possibly know that they were talking about books?

You need to add some context to these sentences. Where are you? What's happening? Who are you talking to?

 

[SoothingDave]

Both of your original sentences are referring to plurals. Books. Ones.

There is no interpretation where you mean a singular good or bad one. It means plural.

If you meant that, you would have to say something like "I bought a good book and many bad ones."

Also, why would you buy a bad book? The way it's written makes it sound as if you already knew it was bad so why buy it at all? I can understand buying a book you've heard is good.
