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.

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)

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.
