Solution

Let the 9 is greatest decimal digit, the greatest 7 digit number would begin with as many nines as possible.
Since there must be 3 different digits in the 7 digits number,
Let begin with five nines and fill the last two places with 8 and 7.
The smallest seven digit number is 1000000
But we need three different digits it will be 1000002
Now,
Let find their sum =9999987+1000002=10999989.
