Answer:

479

Step-by-step explanation:

  1. The number you want is between 100 and 999
  2. At least two of the digits are perfect squares 1 4 9 are the perfect squares.
  3. Units > tens; units are 2 to 9 ; tens are 1 to 8
  4. 1 even in the result; the other two are in 1 3 5 7 or 9
  5. The units digit is larger than the hundreds digit. The units digit is odd.
  6. t = unit - 2. the two odd digits are the tens and the units.
  7. t - h= 3
  8. one of the digits is 7

The units digit cannot be 1 That would make the 10s digit - 1. The tens digit cannot be 9. That would make the units digits 11.

Let's try x79 If that is correct, the hundreds digit is 4 because the hundreds digit is three less than the tens.

Answer: 479

479 is between 100 and 999. 4 and 9 are perfect squares. u>t. 4 is the only even number.
