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