Question

You don't happen to have a pen,___?​

Answer 1

Question: Add Question tag..

You don't happen to have a pen,___?

Answer: You don't happen to have a pen, do you?

_______________________________

General concept:

• If the statement given is negative, the tag must be positive. Similarly if the statement given is positive, the tag must be negative.

Examples:

She doesn't like to play, does she?

He will come, won't he?

________________________________

Basic rules:

• When the verb used in the statement is in the simple present tense, the question tag is formed with "do / does."

Eg.- You sing a song, don't you?

If the verb used in the statement is in the simple past tense, we use "did".

Eg.- They went to the play, didn't they?

When the statement given is negative, the question tag needs to be positive. (As told above)

Eg.- You won't do it, will you?

Thus, Answer to your question:

You don't happen to have a pen, do you?
