You can put this solution on YOUR website! "All digits are odd. I am less than 600 and greater than 400", so this means that the hundreds digit is 5
" My last digit is 7", so the units digit is 7.
"If you add my digits you get 15", if x is the tens digit, then 5+x+7 = 15 ---> x+12 = 15 ---> x = 3
The tens digit is 3
Summary
Hundreds Digit: 5
Tens Digit: 3
Units Digit: 7
Answer: 537
