What is the tag of : their offers sound very attractive , ?

Hi !

Answer :

Their offers sound very attractive, don't they ?

-

verb = offer (present, 3rd p. plural)

auxiliary = do

subject = they (their offers = plural ///  his/her offer = it)

you form a tag  with the auxiliary of the verb and the appropriate subject of the first part of the sentence  in a negative form if the sentence (statement) is positive.

Affirmative tag if the statement is negative

(=> their offers don't sound very attractive, do they ?)
