my 3 digit number...
We are to fill in these three digits:
_ _ _
has a 4 in the hundreds place.
So we fill in the first digit as a 4
4 _ _
the sum of the digits is 6
Since the first digit is 4, the sum of the last
two digits must be 2. So they can either be
two 1's or a 0 and a 2.
it has a greater digit in the tens place than in the ones place
That rules out two 1's. So that means they are a 0 and a 2,
and since the tens digit is greater it must be the 2 and the
ones digit is the 0. So the answer is:
4 2 0
