it is a three digit
whose ten digit is 3
its hundred digit is 4 more than its one digit, which is an odd number less than 5
no two digits are the same
I need help on how to do this. too many years for mommy

if the digits are h,t,u for hundreds, tens, units, then the number is
hdu
Now, just start using the given info:
tens digit is 3, so
hdu = h3u
the ones digit is odd and less than 5. There are only two such numbers: 1 and 3. But 3 is already used, so
hdu = h31
Now, hundreds is 4 more than ones, so
hdu = 531
