Kwan has modeled a number that is
less than 999. His model has twice
as many 100blocks as 10blocks.
It has twice as many 10blocks as
1blocks. What is the number?

421 or 842
That, of course, assumes there are no decimal points involved. Otherwise, the options are limitless.

if a 1 block means ones 10 block means tens and 100 block means 100s then the number would be 842 because 8 is 2 times as much as 4 and 4 is 2 times as much as 2
