If we consider the two sentences:
- On Mondays, near 10% of the workforce report sick;
- On Mondays, nearly 10% of the workforce report sick;
I am inclined to think that the latter is correct. But '10% of the workforce' is a noun-phrase, so the adverb 'nearly' should not logically be there. I saw a few sentences similar to the first, but I am not very convinced they are correct. Couldn't find this in the Wren & Martin. Please correct me if I am wrong.
