The greatest number which on rounding off to nearest thousands gives $$5000$$, is
Correct option is D. $$5499$$
$$\textbf{Identifying the digit in the hundreds place:}$$
As we are rounding off the number to the nearest thousands we need to check the digit in the next smaller place value which is hundreds place.
Given that a number is rounded off to get $$5000$$.
All the numbers given in the options have $$5$$ in the thousands place.
So the digit in the hundreds place should be less than $$5$$.
Also we need the greatest possible number so we should take the biggest digit that is less than $$5$$ which is $$4$$.
So the hundreds place should have $$4$$,
The remaining places should have the highest digit which is $$9$$.
So, $$5499$$ is the required number.
$$\therefore$$ $$\textbf{Option D is correct}$$.
