Let the digits be these 4 blanks to fill in:
_ _ _ _

>>...The sum of my hundreds digit and my tens digit is 15...<<

The only pairs of digits that have sum 15 are {6,9} and {7,8}

>>...My hundreds digit is one less than my tens digit...<<

Therefore the pair is {7,8} so the number is

_ 7 8 _

>>...The sum of my thousands digit and my ones digit is 5...<<

The only pairs of digits that have sum 5 are {0,5}, {1,4} and {2,3}.

>>...my ones digit is one more than my thousands digit...<<

Therefore the pair is {2,3} so the number is

2 7 8 3
