Question 723493
Let x=1000's digit
y=100's digit
z=10's digit
And w=unit's digit
Now we are told that:
w=2x
w=z-1
y= absolute value of z-x
x=1,3,or 5
If x=1, then w=2, z=3 and y=2----No good.
If x=3, then w=6, z=7 and y=4----An Answer
If x=5, then w=10------------------No good
So the answer is:
3476
