Clues only please if anyone can help.
20. Where was Chaucer the first?
30. If 1 = 48, 3 = 13 and 5 = 31, what d6es 6 equal.
70. French slang term for a local bar.

I have an idea for 20 but not 100% sure of the meaning of the question. Is it where he had his first printing press in England or related to his first book.
30. It seems this one has a lot of quizzers wondering.
Thanks in advance.

Thank you baitress. I am not sure exactly what the question is referring to, it could be a few things so I will consider your answer along with my thoughts.

[furrypusscat]

Thanks mallyh, I think there would be a few relieved quizzers if this can be cracked.

Is there a theme to this? I have a possible answer for 70 but can't think of a way to give a clue.
