Total number of people = 1 (project manager) + 7 (team members) + 1 (new team member) = 9


no. of communication channels = n(n-1)/2 = 9 * 8/2 = 36.


Correct Answer is D.

This is pretty straight forward.

Number of Comm. Channels = N (N-1) /2

N= Total Team members=PM+existing members 7 + New member = 9

No. of Comm. Channels = 9* 8 /2 = 36

Yes 36 is the correct answer :-


Total Team Member =8 + 1 Project Manager


9*8/2=36

I agree with the answers. Thankyou for the explanation @ swamy_akella, ChandraR, ambahnaresh.

The formula of communication is straight forward [N*(N-1)/2] but the Questions can be tricky.

Please watch my Video explaning all the different technique's and tricks that you can do with this Formula.
