Shouldn't the answer be D? It says the ticks are equally spaced. So if Y, the fifth tick, is 1.5 then X, the first tick, should be 0.3. Statement 1 is sufficient.

The distance between Y and X, 4 tickets, is 1.2 so X=0.3 and Y=1.5

Statement 2 is also sufficient.

Am I missing something here?

Looking back at this I made the classic mistake of taking in statement 1 when viewing statement 2. The distance between Y and X is 1.2 that could be a range of values that satisfy this equation. X should be 1.3 and Y could be 2.5 and still Y-X=1.2

So Statement 2 is not sufficient.

I hope statement 1 alone is sufficient now unless I have an enlightenment again later today :D
