a is the hundreds digit of the three digit integer x, b is the tens digit of x, and c is the units digit of x. 3a = b = 3c, and a > 0.
What is the difference between the two greatest possible values of x?
Tip: Dont stop till you have exhausted all answer choices to arrive at the correct one.  Pick:
A) 131
B) 292
C) 394
D) 424
E) 969
Ratio of a:b:c= 1:3:1   Two possible greatest single digit values for b are 9 and 6   if b is 9, then x= 393   if b is 6, then x= 262   difference= 393-262=
