Answer 1

punctuate the following when if I said Mina is a very beautiful girl isn't she

Answer 2

Answer:

Meena is a very beautiful girl, isn't she?

Explanation:

I have taken the question as "meena is a very beautiful girl, isn't she" rather than "if i said meena is a very beautiful girl, isn't she​" because that does not make any logical sense.

"Isn't she?" is a question tag, hence it is always followed by a question mark. Meena is a proper noun so the first letter of her name is capital letter.
