This is a classical paradox. The first two errors are obvious: “They” instead of “There” and “errirs” instead of “errors”. Since there are only two errors, the statement that claims ‘three errors’ itself becomes wrong, thereby resulting in the third ‘error’. But the moment we consider this “wrong statement” as an “error”, the statement becomes correct (because there are three errors now), but then the third “error” is no longer there, making the statement false again!

19 + 20 + 21 = 60
