I suppose you already know why statement 1 is not sufficient.

In statement 2, all three small rectangles are of the same dimension. Lets say that dimension is m x n, where m is the width (the shorter side) and n is the length (the longer side).

So, the length of MN = m + n, and the length of KN=m. Also, notice that the length KN is equal to twice the width of the small rectangle. So:

KN = m = 2n

So the ration KN/MN = m/(m+n) = 2n/(2n + n) = 2/3. Statement 2 is therefore sufficient on its own.

Choose B.
