Question 201613
Let,,w,x,y,z,,,be  four  digits  in  order.
.
x=1/4 y
.
y=2w,,,,therefore  x = 1/4 * 2w = w/2
.
z=w
.
rewriting the  digits,,,,,w,,w/2,,,2w,,,w
.
2w  is  "largest"  digit,,,,like  to  set  to  9 but  also  have  a  digit, (w/2)  ,,,therefore  2w =8  is  largest  possible.
.
restating  digits,,,4,,,2,,,8,,,4,
.
checking,  numbers  match  criteria.
