Ben is the project manager for his organization. His project has 26 stakeholders this week and will
have five additional stakeholders next week. How many more communication channels will Ben’s
project have next week?

A.
140

B.
10

C.
325

D.
5

Explanation:
Ben’s project will have 140 more communication channels because of the five additional
stakeholders. To solve the question, you will need to find the current stakeholder communication
channels first, which is (26*25)/2= 325, and then find the difference of the number of channels for
the five additional stakeholders. You can use the formula of N( N-1), where N is the number of
stakeholders. In this example, the formula would read: Total number of communication channels
that Ben will have next = ((31*30)/2)-((26*25)/2 =140
Answer option D is incorrect. Five is the number of additional stakeholders.
Answer option B is incorrect. 10 is the number of communication channels among just five
stakeholders.
Answer option C is incorrect. 325 is the number of current communication channels.
