You can put this solution on YOUR website! i am 900 more than the greatest possible 4-digit even number that can be made using the digits 1, 4, 2, 5. What number am I?
It has to be even so either the 2 or the 4 has to go last.
To make the greatest possible 4-digit even number you have
to pick the largest, 5, to go first, then the next largest,
4, can go second, because you have a 2 to go last, and then
obviously the 1 has to go next to last.
So the largest 4-digit even number that can be made with
1, 4, 2, 5 is 5412.
900 more than 5412 is 6312
