The answer choice says that A but I'm not sure why. Can you provide an explanation?

I think I just figured it out.

If the increase in profits of Company X from the first year to the second year was the same as the increase from the first year to the third year then there must not have been an increase b/w years 2 and 3, hence a 0% change.

OK - Let's start with Statement 2 which only gives the profits in year 1 and year 3. This is obviously not sufficient.

Statement 1: (EDITING) Yes you are correct ggarr. I mis-read this Q. It can be 0% change.

Matrix,

Does my explanation make sense? I also tried picking #s.
I let yr. 1 profits equal 1 and yr. 2 and 3 profits equal 4.
The percent change from yr. 1 to yr. 2 is 300%. The percent change from yr. 2 to yr. 3 was 0%.

I agree with ggarr. I don't think time value of money would apply to this question.

Ggar, you are correct ... I just applied an equation that proves that there's a 0% increase from Y2 to Y3:

Since the increase in profits from Y1 to Y2 was the same as the increase in profits from Y1-Y3, then we can express this as the formula:

[1] (Y2 - Y1)/Y1 = (Y3 - Y1)/Y1

[2] Y2 - Y1 = Y3 - Y1

[3] Y2 = Y3

Thus, since the % change of Y2 = Y3, then there has been a 0% change between Y2 and Y3.

WHy not..

In the first year I profit $10
In the second and third years I profit $11

Increase from the first to second is the same as the increase from the first to third
