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.
