Since they must only lie or only tell the truth, this is an impossible statement, a paradox.
Using your logic that A is a liar, when A says B is a lying monkey, then B must be a truthful human. Then B would be lying to say A is telling truth. No solution.

A correctly stated puzzle would be for A to say, "B is a truthful monkey. I am human."
Then, A is a lying monkey; and B is a lying human.

Using your logic that A is a liar, when A says B is a lying monkey, then B must be a truthful human.

nope, if "B is a lying monkey" is a lie ... then the truth is that:
1. B is a truth telling monkey OR
2. B is a lying human (anything but monkey) OR
3. B is a truth telling human
... any of the 3 options can be true

eg. when you lie that you drank 2 beers last night, actually, you could still have had 1 (or 10)

My question is if A is a monkey, then how did he tell us that he is a man and b is a lying monkey in the first place? I think we have other problems here.

I am not a big fan of this one. The answer chooses to divide the statements. If the whole statement that A makes is a lie, then, it can be because of the first part of the statement where A says that B is a lying monkey, or like the answer assumes, due to both statements being a lie, or the first part can be the truth (which cannot be because of the statement of B) and the second part could be a lie. I think A could be a monkey or a human.

A says: B is monkey and B lies and A is human.
B says: A is telling the truth.

A lies of B is human, or if B tells the truth, or if A is not human.

The answer divides the first statement and concludes that B is a human and B lies, which is fine, but then goes on to say that A is a monkey because A lies. However, A is already lying because of the first part of the statement, therefore doesn't necessarily have to lie about the latter part. A is not lying about the part that B lies either.

If there was a point in the question that said that every sentence is a lie, then the answer would have worked.
