Roundedness Riddle

Dear children,

Next Monday, we will be doing the sub-topic "Rounding off". So to start you off, recap your rounding off to tens and hundreds and work your brain a little with this riddle below!

==
The digits of B have a sum of 27.
Rounded to the nearest ten, B is 9 660.
Rounded to the nearest hundred, B becomes 10 000
What is B?

Regards,
Miss Chan
