Question :
K+L+M+N = 360
K+L = 180
M+N = 180
Find N

1) M=135. N can be found. Sufficient.
2) N = L/2. No idea about M. Insufficient.

Answer is A

I got this wrong in my CAT...

My logic was this:

1) x =135

Since we know a circle is 360 degrees, and K and L contribute 50%, we have 180 degrees left. Since we are given the angle measure of X, we can solve for N

2) N = L/2

If K and L = 50%, then L must equal 90 degrees. If L is equal to 90 degrees, this would equal 25%. If N is half of L, then N = 12.5%

Am I missing something?...
