Answer 2

Hello friend!!!

◆He says "Man is mortal"
Here the quoted part is an universal truth, so the tenses of the quoted part won't change

So the reported speech of this is
• He said that man is mortal

◆He said, "What are you doing?"

Here said changes to asked as the quoted part is a question.
And the tenses of the quoted part also change to past tense. And the reported speech is in such that it no more remains a question.

So the reported speech for this is
• He asked what I was doing.
