The tens digits is half the hundreds digit.
That narrows it down to these four types of numbers
21_, 42_, 63_, 84_
We only need to fill in the blank for the units digit.
The sum of the digits is 14.
21_ is ruled out because you can't put 11 in the right blank.
63_ is ruled out because you can't put 5 in the blank, because
that would make it an odd number 645.
So it's either 42_ or 84_
To make the sum of the digits be 14, it could either be
428 or 842
Two possible answers.
