Official Solution:

In the figure above, what is the largest number of adjacent angles that can be combined to create a sum of 120 degrees?


A. 1
B. 2
C. 3
D. 4
E. 5


We’ll go for LOGICAL because there is a simple logic behind the question.

All the angles together make up a circle, which equals 360 degrees: \(24x = 360\). Since we are looking for 120 degrees, we can divide the equation by 3 and arrive at \(8x = 120\). There aren’t any adjacent angles that can be added to up to create 8, except the angle \(8x\) itself. So the largest number of adjacent angles is 1.


Answer: A

Isn't that the smallest number of adjacent angles? Largest number should be 3 (x + 2x + 3x).

Those would be less than 120 degrees (as x=15 --> x+2x=3x=6*15=90). The question asks for a sum of exactly 120 degrees (i.e. only 8x works).
