2. HOW TO SOLVE COMMUNICATION CHANNELS
QUESTION

3. COMMUNICATION CHANNELS QUESTION
(EASY)
Q.1. John is project manager project is interacting
with six stakeholders. Three new stakeholders
join the project. How many new channels have
been added?
a. 15 channels
b. 21 channels
c. 24 channels
d. 36 channels
Answer: B - 21 channels

4. HOW THE ANSWER IS B - 21 CHANNELS
 The number of communication channels=n(n-1)/2
where n= number of stakeholders
 In this question the project manager is interacting with
six other stakeholders. Therefore there are seven
stakeholders.
 The number of communication channels = 7(6)/2= 42/2=
21 channels.
 Three new stakeholders join. Therefore there are now
10 stakeholders.
 The number of communication channels = 10(9)/2=
90/2= 45 channels.
 So for 21 channels for seven people and now have 45
channels for 10 people.
 Therefore (45-21) =24 new channels have been added.
Hope this clear your concept.

5. COMMUNICATION CHANNELS QUESTION
(TOUGH)
 Q.2. Peter is project manager project is
interacting with six stakeholders. and now there
are new 45 channels added for new
stakeholders, What is total no of stakeholders in
team now.
a. 15 Stakeholders
b. 21 Stakeholders
c. 17 Stakeholders
d. 36 Stakeholders
Ans: C - 17 Stakeholders

6. HOW THE ANSWER IS C - 17 STAKEHOLDERS
Method 1.
 For this sort question how to find Stakeholders count
from Communication Channels
 Find multiplication number to 90 (45*2) like
15*6 =90
18*5=90
10*9=90
 But from above list find that both the multiplication
number should next to each other
 So 10*9 is right option , then for 45 Channels there are
10 is Stakeholder
 Now existing 7 stakeholder including Manager + 10 new
stakeholders = 17 Stakeholders

7. HOW THE ANSWER IS C - 17 STAKEHOLDERS
Method 2.
 Check the each answer and match with channels(45)
and find the solution
 Eg. Total stakeholder are 7
eg. For 15 stakeholders = 15-7= 8 , 8*7/2= 28
eg. For 21 stakeholders = 21-7= 14, 14*13/2= 91
eg. For 17 stakeholders = 17-7= 10, 10*9/2= 45
eg. For 36 stakeholders = 36-7= 29, 36*35/2=630
 So for 17 stakeholders Channels are 45 , Then your
answer is C, Total 17 stakeholders
I have clear the concept both the ways.
