642.
They are all even numbers and they are all in order from greatest to lease. Their sum must add up to 12 also. so 6 +4 +2 = 12.
If you round it to the nearest 1000 you get 642.
Take
each thing they are saying as 1 of your rules to get the number. And
use that to eliminate numbers for example. 1 3 5 7 are all eliminated.
then use numbers to get to 12 that must be even. Finally make sure they
are from greatest to least.
