Answer:
The three-digit numbers with these properties are 850 or 941.
Step-by-step explanation:
Let x be the hundreds digit, y the tens digit, and z the ones digit. The first condition says that
. The second condition is:
the original number is
while the reversed number is
so

Now we have the system

You can divide by 99 to simplify the second equation.

Note that x, y, z must be digits between 0 and 9 and
. If
, then the second equation forces
, for example z=2 so x-2=8, x=10 which is impossible. If z=0, you get x=8, y=5 and the number is 850. If z=1, you get x=9,y=4 and the number is 941.
