• Last digit of 3rd number can be 5 or 0
  but zero is not allowed.
  
  so last digit ( unit place) of 3rd number will be 5.
  
  Last digit of x and y will be odd number.
  
  First digit ( MSD) of x can be 1 only so that 5x remains a 3 digit number.
  
  so possible combinations are
  x= 1*3 or 1*9
  y= **9 or **7
  z= **5
  
  now one can easily get the numbers.

• Dear Parveen,
  
  Already well explained by Dipin.
  
  when u hv known that
  x= 1*3 or 1*9
  Then u know that * can not be 1,9,8,5.
  
  checking possibilities, u can get
  x= 129.
