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
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?...

It has been stated that "Division K and L together contribute 50% of the company's total profit", that means K + L = 180 degrees
It doesn't explicitly say K = L.

Hey assuming that the figure is drawn to scale is what you seemed to miss. I had solved a similar question where it was mentioned that figure is drawn to scale. So yaa
