Hi Nazrulq,

What is the correct answer given.. If I have to choose, I will go for A - 55 communication channel.
To me This question clearly says You are managing a team of 10 people .. so PM + Team

Communication channel = n(n-1)/2
= (11 * 10)/2
= 55

I think unless stated clearly in the question ( also need to carefully read the wordings in the question) we would need to Add PM in Team.

Please let me us know the correct answer and explanation given for this qsn. Hope Manish will also respond soon.

Thanks

Yes I agree with Kavita. 10 people and to manage them you have one PM so N becomes 11.

Applying the n *n-1/2 formula will get you 55
