Select the correct indirect form of the given sentence. Radha said to…

The correct answer is Option (4) → Radha told us that we would get our salary from our office the next day.

Statement with a time word in indirect speech:

Change	Direct	Indirect	Why
Reporting verb	said to us	told us	"Said to" with a listener becomes "told". "Told" takes the listener straight after it.
Joining word	" " (quotation marks)	that	A statement is joined with "that".
Pronoun change	You, your, your	we, our, our	Radha spoke to "us". So "you" becomes "we", and both "your" become "our".
Tense change	will get	would get	"Said" is past, so "will" becomes "would" (would + base form (V1)).
Time and place words	tomorrow	the next day	The report is made later, so "tomorrow" becomes "the next day".
Full sentence	Radha said to us, "You will get your salary from your office tomorrow."	Radha told us that we would get our salary from our office the next day.

Other time words change the same way. Today → that day, yesterday → the day before, now → then. Example: Kabir said, "I am free today." → Kabir said that he was free that day.

Why the Other Options are Incorrect?

Option 1: Radha told us that we would got our salary from our office the next day. — Incorrect. "Would" is always followed by the base verb. "Would got" should be "would get".

Option 2: Radha told us that we will get our salary from our office the next day. — Incorrect. "Will" is not changed. After a past reporting verb it becomes "would".

Option 3: Radha told us that we would get our salary from her office the next day. — Incorrect. "Your office" meant the listeners' office. So it becomes "our office", not Radha's "her office".
