An example:
-Tom read 10 books last week
-Tom? 10 books? Give me a break!(the speaker knows that Tom isn't much of a reader)

-Том прочитал 10 книг на прошлой неделе
-Том? 10 книг? Да брось! (I think there are also some other ways of saying it here but it doesn't come to my head at the moment)

There are also examples of various meanings here. You can try to translate it (or maybe I'll do it later)
