Hope it helps! :)

Answer 2

Sir can either be the head of the postmaster in this case or simply any man. Therefore, to change the sentence into indirect speech, it is necessary to change it.

When changed the sentence will become ‘The postmaster told the man that old Ali was dead, but he could give him his letter.’ This was the sentence if by sir it meant any man.

Now, if the sentence means the postmaster’s senior, then it will change to ‘The postmaster informed his senior that old Ali was dead, but his senior could give him his letter’.
