My friend filed itr 4(presumptive taxation) on his own and he forgot to give f&o transactions details.Now it is found that If f&o transactions are considered,tax audit is applicable for him.He is having professional income and f&o income.my query is as follows:

1.Whether revised itr 3 can be filed ?

2.whether form 3cb3cd can be filed?

3.what consequences he has to face now?

(Note:pls reply for both the situations if return processed or not processed)
