how to change into reported speech if do or did comes in a wh question?

- In changing a 'wh' question to reported speech, the same rules of change of tense apply as in a statement.
- The word order changes as the question becomes a statement in the reported speech.
-'Do, did' are omitted. For example: "Do you know where the kite is kept?", asked Hari.
                                                                                Hari asked if I knew where the kite was kept.( 'If' replces 'do',)
