Final answer:
To convert Ravi's sentence into indirect speech, it becomes 'Ravi told Shila that he could tell her all about him the following day.' This change includes adjustments to tense, pronouns, and time indicators.
Step-by-step explanation:
To change the sentence Ravi said to Shila, "I can tell you all about him tomorrow." into indirect speech, you must adjust it to reflect that the speaker is no longer directly addressing someone. You should also pay attention to the tense, pronouns, and time indicators as they often need to be shifted to align with the change in the point of view.
The indirect speech version of the sentence would be: Ravi told Shila that he could tell her all about him the following day.
