In the figure above, is $$b > a$$? (Note: Figure is not drawn to scale.)

1) $$a = 35$$
2) $$a < 60$$

I assume the picture is meant to display straight lines. The angles in a circle add to 360 degrees, so here 3a + 3b = 360, and a + b = 120. So if we know a, we can find b and certainly answer the question, so Statement 1 is sufficient. If a+b = 120 and a < 60, then b > 60 must be true, so from Statement 2, b > a, and each Statement is sufficient. The answer is D.
