Hi All,

It's looks like all of the other posters in this thread used an algebraic approach to this question, which is fine. It can also be solved rather easily by TESTing VALUES.

To start, we're told that the average (arithmetic mean) of two integers A and B is 8. This mean that the SUM of A and B is 16.

Let's TEST....

A = 0

B = 16

Next, we're told that the average (arithmetic mean) of integers B and C is 13. This means that the SUM of B and C is 26. Since we already have a value for B (it's 16), we now have a corresponding value for C...

C = 10

The question asks for the positive difference between A and C. Since A=0 and C=10, the positive difference is 10.

Final Answer:
