Mark the correct alternative of the following.
The difference between the greatest and the smallest numbers which when rounded off to the nearest thousand as $$9000$$ is?
Correct option is C. $$999$$
We know that the greatest number that when rounded off to the nearest thousand becomes $$9,000 = 9499$$
Smallest number that when rounded off to the nearest thousand becomes $$9,000 = 8500$$
So, the difference between them $$= 9,499 − 8,500 = 999$$
Hence, the difference between the greatest and the smallest numbers which when rounded off to the nearest thousand as $$9000$$ is $$999$$.
