Answer:
Try writing numbers using each of the ten digits exactly once so that the sum of the numbers is exactly 100.
By relaxing one condition or the other,
19+28+30+7+6+5+4=99
19+28+31+7+6+5+4=100
but after a lot of trial an error, it is perhaps worth trying to prove that there is no solution:
If we use two digit numbers, then we'll have whole numbers N (tens) and M (units) where N*10+M=100 and N+M=45. It follows that N*9=55; Therefore N=55/9, which is not a whole number. (From Polya)
Heuristic: If an answer doesn't present itself, think about proving the problem cannot be solved.
